s Product Information

Edition 06/2007

This product information sheet describes the behavior of the above mentioned inverters (Firmware version V3.0), that is not described in the associated documentation, edition 06/2007, Firmware version 3.0.

All inverters

If in sensorless vector control (SLVC) one of the following problems appears

• motor does not ramp up

• setpoint jumps at low frequencies at ramp down

• motor does not ramp down to 0 Hz even if torque limit is set to 0

• the calculated motor temperature (P0621 > 0) shown in r0035 is implausible

this can be caused by faulty values for both, stator and motor cable resistance.

Try the following to solve the problem:

• disconnect the motor from the feeder cable,

• measure the stator resistance and the motor cable resistance with an ohmmeter or better with a wheatstone bridge

• put the values in P0350 (stator resistance) and P0352 (cable resistance),

• then perform "calculation of motor parameters" again with P0340 = 3.

If you don' not get feasible values measuring the stator resistance, use the equivalent circuit data of the motor (this can be can be provided by the motor manufacturer) and write it into the respective parameters (fig 6.1 in Function Manual) or reduce the stator resistance in 5 % steps and perform "calculation of motor parameters" again with P0340 = 3.

Fail-safe inverters

If activating SS1 or SLS, this triggers the STO signal as a pulse. This STO pulse has no influence on the SS1 or SLS function and can be ignored.

CU240S PN

If in HW config of STEP 7 a different telegram type is selected from the telegram type selected in P0922 in the inverter, the inverter trips - by fault - with F00452 (belt failure). If this fault occurs then check the telegram set in HW config and P0922.

Power Modules PM260

With Power Modules PM260 "motor temperature identification" (P0621) only works with a KTY sensor.

General

WARNING This equipment contains dangerous voltages and controls potentially dangerous rotating mechanical parts. Non-compliance with the warnings or failure to follow the instructions contained in this manual can result in loss of life, severe personal injury or serious damage to property. Protection in case of direct contact by means of SELV / PELV is only permissible in areas with equipotential bonding and in dry indoor rooms. If these conditions are not fulfilled, other protective measures against electric shock must be applied e.g. protective insulation. Only suitably qualified personnel should work on this equipment, and only after becoming familiar with all safety notices, installation, operation and maintenance procedures contained in this manual. The successful and safe operation of this equipment is dependent upon its proper handling, installation, operation and maintenance. The power supply, DC and motor terminals, the brake and thermistor cables can carry dangerous voltages even if the inverter is inoperative. Wait at least five minutes to allow the unit to discharge after switching off the line supply before carrying out any installation work. It is strictly prohibited for any mains disconnection to be performed on the motor-side of the system; any disconnection of the mains must be performed on the mains-side of the Inverter. When connecting the line supply to the Inverter, make sure that the terminal case of the motor is closed. When changing from the ON to OFF-state of an operation if an LED or other similar display is not lit or active; this does not indicate that the unit is switched-off or powered-down. The inverter must always be grounded. Isolate the line supply before making or changing connections to the unit. Ensure that the inverter is configured for the correct supply voltage. The inverter must not be connected to a higher voltage supply.

Static discharges on surfaces or interfaces that are not generally accessible (e.g. terminal or connector pins) can cause malfunctions or defects. Therefore, when working with inverters or inverter components, ESD protective measures should be observed. Take particular notice of the general and regional installation and safety regulations regarding work on dangerous voltage installations (e.g. EN 50178) as well as the relevant regulations regarding the correct use of tools and personal protective equipment (PPE).

The control terminals have a maximum tighten torque of 0.25 Nm (2.2 lbf.in) and a nominal cross section of 1.5 mm2 (AWG 14) for cable.

MMC The MMC provides the ability to store parameter sets or firmware versions of an inverter. It is recommended that the SINAMICS-MMC (order number: 6SL3254-0AM00-0AA0) is used for the storage and transfer of parameter sets or firmware versions.

Option port Via the Option port a PC (using the PC Connection Kit) or a BOP is connected to the inverter. With a PC the inverter can be easily parameterized using the commissioning tool STARTER.

Installing/Mounting 4Installing the Control Unit

The CU controls the functions of the PM. The CU cannot be used without a PM, also the PM cannot be used without a CU.

WARNING An inverter can be switched on unintentionally if the installation is not performed correctly. The inverter must be started-up by personnel who are qualified and trained in installing systems of this type.

4.1 Fitting the CU to the PM

Description The Control Unit is snapped on to the Power Module as shown in the figure below. To disconnect the CU push the release button on top of the PM. The process of fitting the Control Unit to the Power Module is the same technique independent from the type of G120 control unit or G120 power module.

Installing/Mounting 4.1 Fitting the CU to the PM


Figure 4-1 Fitting the control unit to the power module

24 V power supply Normally the CU is supplied with 24 V from Power Module. But it is also possible to use an external DC 24 V supply (20.4 V … 28.8 V, 0.5 A). It must be connected to the Control Unit terminals 31 (+ 24 V In) and 32 (0 V In). Some reasons for using an external 24 V power supply are: The PROFIBUS DP interface is required to communicate with the Control Unit when the

Power Module mains power is not present Supply for 24 V encoder

CAUTION

Care must be taken to ensure that the 24 V DC power is connected correctly or damage to the Control Unit may occur. Max. cable length on 24 V DC supply and I/O cables connected to CU must not exceed 10 m. Use of unscreened cables is possible, however we recommend the use of screened cables, in order to fulfill the EMC requirements for the CE marking and fail-safe products (CU240S DP-F).

Note If the CU is externally powered with 24 V DC but the power module is disconnected from the mains supply, the faults F0001 … F0028 are not generated.

Installing/Mounting 4.2 Connecting a CU240S via Terminals


4.2 Connecting a CU240S via Terminals

Description To have access to the control terminals, the terminal cover must be removed, as shown in the figure below. The control terminals have a maximum tighting torque of 0.25 Nm (2.2 lbf.in) and a nominal cable cross section of 1.5 mm2.

Figure 4-2 Removing the Control Unit terminal cover

The terminals of the CU240 control units are combined to terminal blocks. They can be detached from the control unit, as shown in the figure below.This allows the control units to be swapped out for another of the same type without the need for rewiring.



Figure 4-3 Removing the two-part connectors with a CU240S DP as example

After all the wiring of the control unit is completed - ensure that the terminal cover is replaced.

Terminal wiring examples for the Control Unit CU240S

Note To control the CU240S DP, CU240S DP-F or CU240S PN via terminals is also possible, but in this case the parameter settings for command and setpoint source have to be changed.

In this section examples of controlling a SINAMICS G120 inverter with a CU240S via terminals are shown.

CAUTION Use of unscreened cables is possible, however we recommend the use of screened cables in order to fulfill the EMC requirements for the CE marking and fail-safe products (CU240S DP-F).

Control with the default settings Frequency setpoint and an additional setpoint via terminals

(AI0 and AI1 used as voltage inputs) Frequency setpoint and an additional setpoint via terminals

(AI0 and AI1 used as current inputs)



Control with the default settings When shipped from the factory the G120 inverter (Control Unit and Power Module) must not be operated before the values depending on the specific PM are read into the CU. This can be done via: Downloading a valid parameter set (by MMC, STARTER, or BOP) Quick commissioning A factory reset To operate the inverter with the basic settings (e.g. after factory reset, without additional parameterization or DIP switch setting), the following conditions have to be fulfilled: The rated current of the inverter is at least as great as the rated current of the motor. The power range of the inverter matches the power range of the motor. The controlled motor is a 4-pole motor (best Siemens 1LA7). The rated motor frequency is 50 Hz, power dimension unit is kW.

Control settings Digital and analog inputs for commands and setpoints are parameterized for a cabling as shown in the block diagram of the CU240S in the operating instructions. Furthermore the state of the inverter is monitored via digital and analog outputs.

4.2.1 Setting Frequency Setpoints via the DIP Switches

Setting Frequency Setpoints via the DIP Switches The general I/O DIP switches 1 and 2 are used to configure the analog inputs (AI). For using AI0 and AI1 as voltage inputs set DIP switches 1 and 2 to OFF position.

Description The function of the PROFIBUS DP interface is to provide a PROFIBUS DP-based link between inverters of the SINAMICS G120 product range and higher-level automation systems e.g. SIMATIC S7.

4.4.1 Connecting the PROFIBUS DP

Connecting the Inverter to the PROFIBUS DP network The inverter is to be connected to the PROFIBUS DP network via a sub-D socket on the CU240S DP or CU240S DP-F. The pins of the socket are short-circuit-proof and isolated.

External 24 V supply If the PROFIBUS DP interface is required to communicate with the Control Unit when the Power Module mains power is not present, a 24 V supply must be connected to the Control Unit terminals 31 (+ 24 V In) and 32 (0 V In).

Maximum cable length The PROFIBUS system can handle up to 126 stations. To run all these stations the PROFIBUS system is divided into segments. All segments have to be connected via repeater. The maximum number of stations on any segment must not exceed 32. The maximum cable lengths are dependent on the baud rate (transmission speed). The maximum cable lengths specified in the table below can be guaranteed only with PROFIBUS bus cables (for example, Siemens PROFIBUS bus cable, order number 6XV1830-0EH10).

Baud rate Max. cable lengths for one segment 9.6 kbaud … 187.5 kbaud 1000 m (3280 ft)* 500 kbaud 400 m (1312 ft)* 1.5 Mbaud 200 m (656 ft)* 3 Mbaud … 12 Mbaud 100 m (328 ft)* ∗ Repeaters can be installed to increase the length of a segment.

Cable installation rules During installation the bus cable must not be: twisted stretched or compressed. Supplementary constraints as regards electromagnetic compatibility must also be observed.

Bus connector To connect the PROFIBUS cable to the PROFIBUS DP interface, a bus connector of one of the types described in the following table is recommended.

Note

We recommend only these two connectors since they can be used without difficulty for all SINAMICS G120 models and are completely compatible in terms of outgoing cable unit angle.



PROFIBUS terminator Each bus segment must have a resistor network at both ends as shown in the figure below.

Figure 4-4 PROFIBUS network with bus termination

You have two options to terminate the bus connection: Terminator switch on the recommended PROFIBUS connector The switches of the bus terminator provides both the 220 Ω termination and the 390 Ω biasing. The 390 Ω biasing maintains the potential difference between the signals in the PROFIBUS network cables.

• Terminator switch on the housing of the SINAMICS G120 (see section "Layout and Block diagram")



Caution Never use both ways to terminate the bus connection. This can interfere the communication.

WARNING

It must be ensured that any node, where the biasing components of the bus are connected, is powered at all times in which the bus is in operation.

Removing a bus connector You can remove the bus connector with looped-through bus cable from the PROFIBUS DP interface at any time without interrupting the data exchange on the bus. Only the final node must be terminated.

4.4.2 Screening the bus cable and EMC precautions

Description The following EMC-related precautions must be taken to ensure interference-free PROFIBUS DP operation.

Screening The screen of the PROFIBUS DP cable must be connected in the bus connector. Additional screening is provided using a screen clamp on the bus cable screen which must make 360° contact with the protective earth. The solid copper core must not be scored when the insulation is removed from the core ends. You must also ensure that the screen of each bus cable is connected to protective earth at both the cabinet entry point and in the inverter housing.



Note The bus cables must be internally twisted and screened, and installed separately from power cables with a minimum distance 20 cm (7.8 inches). The braided screen and underlying laminated foil screen (if applicable) must be connected in a 360°, positive connection at both ends, that is, the screen on the bus cable between two inverters must be connected to the inverter housing at both ends. The same applies to the screen of the bus cable between the PROFIBUS DP master and inverter. Crossovers between bus and power cables must be laid at an angle of 90°.

Equipotential bonding Differences in potential (for example, due to different mains supplies) between the inverters and the PROFIBUS DP master must be avoided. Recommended equipotential bonding cables:

– 16 mm2 Cu for equipotential bonding cables up to 200 m long – 25 mm2 Cu for equipotential bonding cables of over 200 m long.

Equipotential bonding cables must be routed as close as possible to signal leads; this means that the area between the bonding conductor and signal lead is as small as possible.

Equipotential bonding cables must be contacted in a 360° connection with the earth electrode/PE conductor.

Commissioning 5Overview

A G120 inverter is composed of the Power Module and the Control Unit. After snapping the Control Unit on to the Power Module for the first time, the devices must identify each other. To indicate, that the Power Module and the Control Unit are not yet identified, F0395 is displayed. For further information to the message F0395, refer to section "Message F00395". The G120 inverter provides two options for commissioning: Single commissioning One inverter is parameterized for commissioning with an individual parameter set. Usually, you use the STARTER or BOP for single commissioning. Series commissioning Several inverters are parameterized for commissioning via download of a complete parameter set. Usually, you use the MMC for series commissioning.

Note We recommend commissioning via STARTER. The commissioning process using STARTER is driven by dialog boxes and will not be interpreted in this manual. This manual describes the parameter related commissioning via BOP.

Interfaces The G120 inverter provides different communication interfaces. The following figure provides you an overview:

Commissioning 4.6 Installation Check List


Figure 5-1 Communications interfaces

Commissioning 5.1 Single Commissioning


5.1 Single Commissioning

Overview For single commissioning, you set the parameter of the inverter manually. You use BOP (Basic Operator Panel) or STARTER (Commissioning software via PC) for commissioning.

Note We recommend commissioning via STARTER. The commissioning process using STARTER is driven by dialog boxes and will not be interpreted in this manual. This manual describes the parameter related commissioning via BOP.

Settings of commissioning Commissioning the G120 inverter comprises different settings and kinds of single commissioning. The following list provides you an overview: Basic commissioning

– Quick commissioning – Motor data identification – Speed control optimization

Further settings for commissioning – Calculating the motor/control data – Commissioning the application – Reset parameters to factory settings – Commissioning the fail-safe functions (only in fail-safe applications)

For detailed information to the settings of single commissioning, refer to the section "Commissioning with BOP".

Factory settings The inverter is delivered with identical factory settings for all CU240S Control Units; except the following settings: Command source Setpoint source Values depending on the Power Module

The factory settings of the Power Modules are specific for the type of PM. For details to the factory settings, refer to the Parameter Manual.

Note After the first power on, the fault F0395 will appear. This means, no commission is until now implemented. After confirming the message, you can proceed commissioning.

Commissioning 5.2 Series Commissioning


5.2 Series Commissioning

5.2.1 Common Information to Series commissioning

Description Series commissioning means transferring the parameter set from one inverter into a number of other inverters. This provides fast commissioning for identical applications, e. g. series machines or group inverters.

Components for series commissioning Commissioning the G120 inverter can be done in different ways. The following list provides you an overview: Series commissioning with MMC Series commissioning with BOP Series commissioning with STARTER For detailed information to series commissioning, refer to the chapters "Commissioning with BOP", Commissioning with MMC", and "Commissioning with STARTER".

Order of series commissioning The series commissioning is divided into the following steps: Creating a valid parameter set Uploading this parameter set Downloading of the uploaded parameter set into the next inverter An appropriate parameter set can be created by parameterizing an inverter via BOP or STARTER.

CAUTION Parameter download between different types of Control Units and of different firmware versions is not recommended. It is possible to download parameter sets from different Control Unit types, however, as the parameter sets might differ, the user is fully responsible for the consistency of the downloaded parameter set. Therefore, the customer has to confirm his responsibility in case of an automatic download by acknowledging F0395. During download of a parameter set from an MMC to the EEPROM of the Control Unit CU240S (e.g. during serial commissioning) you have to note that the LEDs are flashing correctly. If the Control Unit CU240S is in a fault state, the LEDs indicate this fault state with higher priority than the download. It is not sure that the parameter set is downloaded correctly.



WARNING

For series commissioning, all of the communication interfaces as well as also the digital and analog interfaces are re-initialized. This results in a brief communications failure or causes the digital outputs to switch. Potentially hazardous loads must be carefully secured before starting a series commissioning. Potentially hazardous loads can be secured as follows before starting series commissioning: • Lower the load to the floor, or • Clamp the load using the motor holding brake.

Note

Upload Before the upload starts, the parameters will be copied from RAM to EEPROM Manual and automatic download With a manual download all necessary parameters excluding the fail-safe parameters (only with CUs with fail-safe functions) are downloaded into the inverter. How to perform a manual download is described in the following section. With an automatic download even the fail-safe parameters are downloaded into the inverter. An automatic download can only be performed with an MMC. An automatic download can be performed at Start-up or by swapping an inverter component (CU or PM), details are described in the following sections and in the chapter "Operation" of this manual.

Note

Restrictions to be considered when performing upload and download: • Only the parameter set stored in the EEPROM of the inverter is uploaded. • Fail-safe parameters cannot be uploaded via BOP or STARTER. • Once the upload or download procedure has started, it should not be interrupted. • Parameter download from a standard CUs to a CUs with fail-safe functions and vice

versa is not possible. • During the up or download all LEDs are flashing (the "BF" LED is not relevant). After

finishing that process successfully the "RDY" LED is on. • During the upload process any data already held by the BOP is overwritten. • If the download fails, the inverter will not function correctly and the "SF" LED (red) is on.

– Possible fault messages in case of download failure with BOP F0051, F0055, F0056, F0057 or F0058

– Possible fault messages in case of download failure with MMC F0051, F0061, F0062 or F0063



NOTICE After upload and download of parameters between differing Control Units, the parameter settings must be checked. Parameter download from a different CU might fail with F0063 if parameters cannot be downloaded (Check P949 for the (first) parameter number which cannot be downloaded). If F0061 or F0063 occurs during startup it cannot be cleard except via a power cycle.

5.2.2 Upload and Download of Parameter Sets

Upload of parameter sets With an upload, a parameter set can be saved in one of the following devices: PC (via STARTER) MMC BOP

Note The file format for the MMC is FAT. Any other format, such as FAT32 or NTFS are not compatible with uploading and downloading parameter sets from the inverter. Formatting can be accomplished using the DOS command line as follows: C:\>format volume /FS:FAT - where volume has to be replaced by the name of the MMC drive, for example A. Please keep in mind that formatting will delete all the contents of the MMC.

An upload can be triggered via PROFIBUS BOP STARTER A detailed description is given in "Series Commissioning" in the commissioning section.

Download of parameter sets In the case of a parameter download it is important to distinguish between the following possibilities: Manual download Automatic download.



CAUTION

Parameter download between different types of control units and of different firmware versions is not recommended. Basically, it is possible to download parameter sets off different CU types, however, as the parameter sets might differ, the user is fully responsible for the consistency of the downloaded parameter set. Therefore, the user has to take the responsibility in case of an automatic download by acknowledging F0395. During download of a parameter set from a MMC to the EEPROM of the Control Unit CU240S (e.g. during serial commissioning) you have to note that the LEDs are flashing correctly. If the Control Unit CU240S is in a fault state, the LEDs indicate this fault state with higher priority than the download. It is not sure that the parameter set is downloaded correctly.

Manual download A manual download can be performed similar to an upload via PC (STARTER) MMC BOP It can be triggered like upload via PROFIBUS BOP STARTER With a manual download a parameter set without the fail-safe parameters is downloaded from one of the above mentioned devices into the inverter. The manual download depends as follows on the settings of P8458.

Automatic download An automatic download needs a MMC to be performed. It is not possible to perform an automatic download from a PC or from the BOP. The automatic download runs as follows according to the settings in P8458 after power cycle or a after a swap (see "Start-up behavior" in this section).

Contrary to a manual download even the fail-safe parameters are downloaded with an automatic download.

Note Manual and automatic download With a manual download all necessary parameters excluding the fail-safe parameters (only with Cus with fail-safe functions) are downloaded into the inverter. A detailed description is given in "Series Commissioning" in the commissioning section. With an automatic download even the fail-safe parameters are downloaded into the inverter. An automatic download can only be performed with an MMC at Start-up or by swapping an inverter component (CU or PM). A detailed description is given in "Start-up behavior" of this section.

Note If the inverter is to be commissioned from a defined state, it can be reset to its default settings by performing a factory reset (see section "Reset Parameters to Factory Settings")

NOTICE Parameters can be changed independent whether an MMC is plugged in or not. Depending on the settings in P8458 after power cycle the parameters from EEPROM or MMC are used for start up. The customer has to take care that the parameter set used for start-up is valid (see also "Start-Up Behavior").

WARNING

In case of automatic parameter download from the MMC at start up, F0395 will be generated. Clearing F00395 is described in the section "Message F00395" of this manual.

Commissioning 5.4 Message F00395


5.4 Message F00395

Description The message F00395 is displayed to prompt you to check the parameter set. In case of standard CUs you accept the responsibility for a parameter set by confirming F00395. In case of fail-safe CUs you have to carry out an acceptance test.

F00395 does not indicate an inverter fault.

Confirming F00395 on standard CUs For CUs without fail-safe function, you confirm F00395 in one of the following ways: Via a factory reset Via the function key FN on the BOP Digital input or PLC signal (depends on the settings of P0700) Setting P7844 = 0

Confirming F00395 on fail-safe CUs For CUs with fail-safe functions, it is necessary to do an acceptance test to confirm F00395. For details to the acceptance test (refer to the "Commissioning the Fail-Safe functions" section in this manual. You confirm F00395 on fail-safe CUs in the following way: P0010 = 30 P9761 = safety password P7844 = 0 Carry out acceptance test

Procedures which require a release of a parameter set via F00395 A Control Unit indicates F00395 in the following states: After the first power ON After an automatic download After a swap of the Control Unit

Note The BOP sometimes displays "bUSY" when changing parameter values. This means that the inverter is presently handling another higher-priority task.



5.5.2 Overview Commissioning with the BOP

Commissioning overview A differentiation is made between the following scenarios when commissioning the inverter via BOP:

Single commissioning Basic commissioning

– Quick commissioning – Motor data identification – Speed control optimization

Further settings for commissioning – Calculating the motor/control data – Commissioning the application – Reset parameters to factory settings

Commissioning the fail-safe functions (only in fail-safe applications)

Series commissioning Uploading the parameter set Downloading the parameter set When commissioning, initially, a quick or series commissioning should be performed. If there is no appropriate parameter set available for series commissioning, a quick commissioning must be carried-out. With the function "quick commissioning", the inverter is adapted to the motor and important technological parameters are set. The function "commissioning the application" should only be performed, if the inverter–motor combination provides a satisfactory result.

5.5.3.2 Motor Data Identification

Parameter settings

WARNING The motor data identification routine MUST not be used for loads which are potentially hazardous (for example, suspended loads for crane applications). Before the motor data identification routine is started, the potentially hazardous load must be carefully secured (for example, by lowering the load to the floor or by clamping the load using the motor holding brake).

Parameter Description P0625 = … Ambient motor temperature (entered in °C)

The motor ambient temperature is entered at the instant that motor data is being determined (factory setting: 20 °C). The difference between the motor temperature and the motor ambient temperature P0625 must lie in the tolerance range of approx. ± 5 °C.

If not the motor must be allowed to cool down. P0010 = 0 Commissioning parameter filter*

Check if P0010 = 0 (Ready) P1900 = 3 Select motor data identification*

0: Disabled (default) 2: Identification of all parameters in standstill. 3: Identification of all parameters in standstill including saturation curve

ON command Start motor data identification Once P1900 ≠ 0, alarm A0541 is generated that states, the next ON command will initiate the motor data identification. When the ON Command is given, current flows through the motor and the rotor aligns itself. Note: When motor data identification is complete A0541 will be cleared and P1900 will be set to zero.

OFF1 In order to set the inverter into a defined state, an OFF1 command must be issued before the next step. With the OFF1 command the motor data identification is finished.



5.5.3.3 Speed Control Optimization

Parameter settings Parameter Description P0010 = 0 Commissioning parameter filter*

Check if P0010 = 0 (Ready) P1960 = 1 Speed control optimization

0: Disable (default) 1: Enable

ON command

Start Speed control optimization We recommend the Speed control optimization if vector mode (P1300 = 20 or 21) is selected. Once P1960 = 1, alarm A0542 is generated, that states, the next ON command will initiate the optimization. If there is a problem with speed control optimization due to instability the drive may trip with fault F0042, because no stable value has been obtained on the ramp up within a reasonable time. Note: When Speed control optimization is complete A0542 will be cleared and P1960 will be cleared to zero.

5.5.4 Further Settings for Commissioning

5.5.4.1 Calculating the Motor and Control Data

Overview Internal motor/control data is calculated using parameter P0340 or, indirectly using parameter P3900 or P1910. The functionality of parameter P0340 can, for example, be used if the equivalent circuit diagram data or the moment of inertia values are known. The following settings are possible for P0340:

0 No calculation 1 Complete parameterization 2 Calculation of the equivalent circuit diagram data 3 Calculation of V/f and Vector control 4 Calculation of the controller settings

For the complete parameterization (P0340 = 1), in addition to the motor and control parameters, parameters are also pre-assigned which refer to the motor rated data (for example, torque limits and reference quantities for interface signals). A complete list of all of the parameters depending on P0340 is included in the parameter manual.



Note When exiting quick commissioning with P3900 > 0, internally P0340 is set to 1 (complete parameterization). For the motor data identification, after the measurement has been completed, internally P0340 is set to 3.

Performing the calculation of motor and control data via BOP Parameter Description Setting P0340 = 1 Calculation of motor parameters

This parameter is required during commissioning in order to optimize the operating behavior of the inverter. For the complete parameterization (P0340 = 1), in addition to the motor/control parameters, parameters are pre-assigned which refer to the rated motor data (e.g. torque limits and reference quantities for interface signals). A list of the parameters, which are calculated, depending on the setting of P0340, are included in the parameter list. 0: No calculation 1: Complete parameterization (default) 2: Calculation of equivalent circuit data 3: Calculation of V/f and Vector control data 4: Calculation of controller settings only

If additional catalog data is known enter the data in P0341, P0342 and P0344. P0341 = … Motor inertia [kg*m2] P0342 = … Total/motor inertia ratio P0344 = … Motor weight (entered in kg) If the ECD data is known, enter the data in P0350, P0354, P0356, P0358, P0360. If the ECD data is not known, then: Set P0340 = 4. To calculate the controller settings and skip to END. P0350 = … Stator resistance (line) (entered in Ω)

Stator resistance in Ω of the motor which is connected (line). This parameter value doesn't include the cable resistance.

P0354 = … Rotor resistance (entered in Ω) Defines the rotor resistance of the motor equivalent diagram (phase value).

P0356 = … Stator leakage inductance (entered in mH) Defines the stator leakage inductance of the motor equivalent diagram (phase value).

P0358 = … Rotor leakage inductance (entered in mH) Defines the rotor leakage inductance of the motor equivalent diagram (phase value).

P0360 = … Main inductance (entered in mH) Defines the main (magnetizing) inductance of the motor equivalent diagram (phase value).

P0340 = 3 Calculation of motor parameters 3: Calculation of V/f and Vector control (default) All of the parameters, dependent on the ECD data are calculated and, in addition, the controller settings (P0340 = 4).

END The motor parameters have been calculated and it is now possible to return to the additional parameterization in the Section "Commissioning the Application".



5.5.4.2 Commissioning the Application

Overview After the motor - inverter combination has been commissioned using quick commissioning, the following parameters should be set according to the requirements of your specific application. As an example, the following points should be considered: Functional requirements of the inverter (for example, closed-loop process control with PID

controller) Limit values Dynamic requirements Starting torques Load surge requirement Overload Diagnostics For information to functions refer to the Function Manual.

Commissioning the application - step-by-step description The parameters designated with an "*" offer more setting options than are listed here. Refer to the Parameter Manual for additional settings. For detailed information refer to the Function Manual.

P0014 = … Store mode 0: Volatile (RAM) (default) 1: Nonvolatile (EEPROM)

P0210 = … Supply voltage (enter the voltage in V) This parameter enters the real line supply voltage to which the Inverter is connected. Only necessary if P1254 = 0 (default: P1254 = 1).

P0290 = 2 Inverter overload reaction This defines the response of the Inverter to an internal over temperature. 0: Reduce output frequency 1: Trip (F0004) 2: Reduce pulse frequency and output frequency (default) 3: Reduce pulse frequency then trip (F0004)

Note If P0014=0 you can always transfer all parameter values from RAM into EEPROM via P0971. The duration of the data transfer depends on the number of changed parameters. The data transfer can last up to 3 minutes. During the data transfer, BOP displays "bUSY".

Pulse Encoder Parameter Description Setting P0400 = 0 or P0400 = …

P0604 = … Threshold motor temperature (0 °C … 220 °C, default 130 °C) Enter the warning threshold for motor over temperature protection. The trip temperature threshold (warning threshold + 10 %) is where either the inverter is tripped or Imax is reduced (P0610).

P0610 = 2 Motor I2t temperature reaction Defines the reaction when the motor temperature reaches the warning threshold. 0: No action, only a warning 1: Warning and Imax reduced (this results in a reduced output frequency) 2: Warning and trip (F0011) (default)



Temperature calculation without sensor In the vector control mode (P1300 = 20/21/22/23) Temperature calculations is possible without sensor. The following parameters have to be set.

Parameter Description (Parameter name and factory setting (if not variable) in bold) Setting P0621= 1 Motor temperature identification after restart

0: No identification (default) 1: Temperature identification only at first "motor on" after power cycle 2: Temperature identification at each motor on.

P0622 = … Motor magnetizing time for temperature identification after stator restistance identification This parameter will be initialised with a value for one calculating cycle of the motor temperature. It depends on the identified rotor time constant. Due to accuracy reasons this calculation may be performed several times.

The rounding times are recommended, to avoid abrupt responses and so to minimize stress to the mechanical system. The ramp-up and ramp-down times are extended by the component of the rounding ramps.



Further parameters to set before finishing the application commissioning The following parameters should be configured for each application.

Parameter Description Setting P1800 = 4 Pulse frequency (kHz)

The pulse frequency can be changed in 2 kHz steps. The range extends from 4 kHz up to 16 kHz. The complete inverter output current at 50 °C is reached with 4 kHz. The maximum output frequency depends on the pulse frequency. Operation up to 266 Hz is possible with a pulse frequency of 4 kHz. If a higher output frequency is required, then the pulse frequency should also be increased (10 kHz pulse frequency - maximum output frequency of 650 Hz) If low-noise operation is not required, then the inverter losses and the high-frequency disturbances emitted by the inverter can be reduced by selecting lower pulse frequencies.

P2000 = 50 Reference frequency (Hz) The reference frequency in Hertz corresponds to a value of 100 %. This setting should be changed if a maximum frequency of higher than 50 Hz is required. NOTE: This scaling acts on the maximum frequency of the analog setpoints, the fixed frequencies and the motorized potentiometer. All these values refer to 100 %.

P2001 = 1000 Reference voltage (V) The reference voltage in Volts (output voltage) corresponds to a value of 100 %. NOTE: This setting should only be changed if it is necessary to output the voltage with another scaling.

P2002 = … Reference current (A) The reference current in Amperes (output current) corresponds to a value of 100 %. Factory setting is 200 % of the rated motor current (P0305). NOTE: This setting should only be changed if it is necessary to output the current with another scaling.

P2003 = … Reference torque (Nm) The reference torque in Newton-meters corresponds to a value of 100 %. Factory setting is 200 % of the rated motor torque, determined from the motor data, for a constant motor torque.NOTE: This setting should only be changed if it is necessary to output the torque with another scaling.

P2004 = … Reference power (kW or hp) The reference power in kW or hp corresponds to a value of 100 %. Factory setting is 200 % of the rated motor power at constant motor torque. This setting should only be changed if it is necessary to output the power with another scaling.

Finishing the application commissioning Parameter Description Setting P0971 = 1 Transfer data from RAM to EEPROM

0: Disabled (default) 1: Start data transfer, RAM → EEPROM All of the parameter changes are transferred from RAM (volatile) into the EEPROM (nonvolatile, settings are not lost with power off). While the transfer is active, "bUSY" will be displayed on the BOP. Once the transfer is completed P0970 will be set internally to "0" and the "P0970" will be displayed. Note: Data transfer RAM → EEPROM is not necessary when the commissioning is performed via the BOP, because all parameter changes via BOP are stored as well in RAM as in EEPROM immediately.



5.5.4.3 Reset Parameters to Factory Settings

Overview With a factory reset via P0970 the initial state of the all the inverter parameters can be re-established. The factory setting values are designated as "Factory setting" in the Parameter Manual. For further information, refer to the section "Factory Settings of the CU240S Control Units" in this manual.

Note When resetting the parameters to the factory setting, the communications memory is re-initialized. This means that communications are interrupted for the time it takes to perform the reset.

WARNING

Parameter reset in case of CUs with fail-safe functions Parameters that don't relate to fail-safe functions are reset with P0970 = 1. To reset parameters that relate to fail-safe functions an additional parameter reset with P0970 = 10 must be performed. This parameter reset is password protected. In case of a parameter reset with P0970 = 10 an acceptance test necessary.

Reset to the factory setting Parameter or action Description P0003 = 1 User access level*

1: Standard: Allows access into most frequently used parameters. P0004 = 0 Parameter filter

0: All parameters P0010 = 30 Commissioning parameter*

30: Factory setting, parameter transfer P0970 = 1 Factory reset*

1: Parameter reset to the default values BUSY (on BOP) Progress bar (STARTER)

When the factory reset has been finished, P0970 and P0010 are set to 0 and the BOP changes back to the standard display.

Note The following parameters will not be changed with a factory reset: • P0014 Store mode • P0100 Europe / North America • P0201 power stack code number • Communication parameters (USS and PROFIBUS settings) • Data depending on actual Power Module



5.5.5 Commissioning the Fail-Safe Functions

Available fail-safe functions Safe Torque Off (STO) Safe Stop 1 (SS1) Safely Limited Speed (SLS)

Command source for fail-safe functions As command source for the fail-safe signals STO, SS1 and SLS either the fail-safe terminals (60 … 63) or PROFIsafe can be used (see p9603 and p9803).

WARNING PROFIsafe address The PROFIsafe address is per default identical to the PROFIBUS address. If the PROFIsafe address needs to be changed, it has to be done as well in P9810 of the inverter as in the higher level control system (in case of SIMATIC S7 in HW config), otherwise F1640 will occur.

Note

Via terminals two of the three fail-safe functions (STO, SS1 and SLS) can be used. Via PROFIsafe all three functions are available.

Commissioning parameters regarding fail-safe functions Parameters regarding fail-safe functions can only be accessed on a Control Unit with fail-safe functions, on a Standard CU this parameters are not available. For safety reasons parameters are handled by pairs and stored on two separate processors within the CU with fail-safe functions. When commissioning of fail-safe functions is completed, checksums for each processor data are created. These checksums are permanently compared. If they differ, the inverter initiates a latched safe torque off (LSTO) state and stops the system. The access level of the fail-safe function parameters is 3, therefore set P0003 = 3, when using a BOP. To enter the commissioning mode for fail-safe functions set parameter P0010 = 95. When the safety commissioning mode is initiated a password must be set in parameter P9761. The default password for the system is 12345, it is highly recommended that this password is changed to ensure complete security of the fail-safe function parameters. More detailed description of this process is given in the following flow charts. The commissioning process of fail-safe functions would normally be accomplished with the use of either the STARTER software or the optional Basic Operator Panel (BOP).



When a parameter is modified, the relevant value is transmitted to the relevant processor in the CU. The value is transmitted back to the user interface and can be checked by the processor and the user for correctness. To complete commissioning of fail-safe functions use setting P3900 = 10, which accepts all the changes to the fail-safe parameters. All values stored on both processors are checked and if no discrepancies are found the inverter state will change from "safety commissioning" to "ready". If, however, a discrepancy is found safety commissioning can not be finished. The fault number will be shown in r0947. In this case interrupt the safety commissioning with P3900 = 11 to reload to the former stored settings. To reset all fail-safe parameters to their default values perform a factory reset of fail-safe parameters with P0970 = 10. It is also recommended to perform a factory reset of fail-safe parameters with P0970 = 10, if a fault has been made during safety commissioning, and the system is in an undefined state. When changing fail-safe parameters, each parameter will be written to the P1 processor and its equivalent parameter to the P2 processor, for example: P9603 selects the required safe digital input terminals or PROFIsafe communications for

P1 processor. P9803 selects the selection of the required safe digital input terminals or PROFIsafe

communications for P2 processor. Example Select PROFIsafe communication: To select the PROFIsafe communications, following has to be set: 1. P9603 = 128. 2. The system reads the change and processes the information to the drive processor

memory and verifies that the information has been received correctly. 3. P9803 = 128. 4. The system reads the change and processes the information to the communication

processor memory and verifies that the information has been received correctly. 5. Once both write actions have been verified by the system, a checksum is created. When commissioning has been completed, a checksum for all the data held in both memories is created and continually checked to verify the integrity of the data.

NOTICE Behavior of inverter on completion of commissioning The following behavior should be noted when commissioning the inverter: • After commissioning the fail-safe functions the fail-safe parameters are automatically

stored in the RAM and EEPROM. • If an MMC is plugged into the CU, this is not affected by normal commissioning or

commissioning the fail-safe functions. • To save the EEPROM content on an MMC, an upload from the inverter to the MMC has

to be performed. • After commissioning the fail-safe functions, an acceptance test must be carried out.

s 0.005 0.000 1.000



Test stop interval setting Parameter Description Unit Default Min. Max. P9659 = … SI maximum time until test stop*

The time interval between test stops is specified in this parameter. The remaining time until a test stop is required is shown in r9660. When r9660 reaches zero, the time interval has expired and warning A1699 is activated. The warning solely informs that a test stop is required. The user should activate a test stop on the next occasion. The drive functionality will not be affected by the warning. The test stop is activated in the following cases: • after each power-up • on selecting the STO when Bit 01 in P9601/P9801 is set • when leaving the latched safe torque off (LSTO). During the test stop the shutdown paths are checked and a processor selftest runs. The timer for the forced dynamisation (see r9660) is reset to the default value specified in P9659 and warning A1699 is cleared under the following conditions: • after reducing P9659 below the current value in r9660, • after each power-up • on selecting the STO when Bit 01 in P9601/P9801 is set and the

test is complete • when leaving the LSTO when the test is complete. The default value is 8 hours. Note: For safety reasons, it is necessary to initiate the safe standstill as a test at intervals of maximum one year in order to check the operability of the fail-safe system. Thus, at the latest one year after the last activation of the safe standstill the inverter sets a status bit (r9772, Bit 15) and generates warning A1699. The process control (i.e. PLC) must then initiate the STO at the next opportunity, for example, when the drive has already a short phase with zero speed. Provided the dynamisation has not been deactivated (see parameters P9601/P9801, Bit 01), the fail-safe hardware is tested once the safe standstill is active. If the inverter returns the "Safe torque off (STO) selected" (r9772, Bit 01) status signal, the safe standstill can be released again since part of the test is continued in the background. The immediate switch-on will be inhibited for approximately 2.4 seconds. Once the self test is complete the dynamisation bit (Bit 15 of r9772) is cleared automatically. The higher level control (i.e. PLC) must log the setting and clearing of the status bit and the dynamisation bit. To detect errors while writing and storing safety-relevant data, the control should fetch cyclically at 8 hour intervals all safety-related parameters and compare them with the expected values. Should there be a difference, the fail-safe signals (STO or SS1) should be used to initiate a safe standstill and to issue a fault message. This action must also be logged appropriately.

h 8.0 0.1 8760.0



Safe Stop 1 setting Parameter Description Unit Default Min. Max. P9680 = … SI braking ramp delay

Time [in ms] between selecting the safe braking ramp (SBR) and the activation of the monitoring ramp. The output frequency is compared to the frequency of the monitoring ramp when the SBR is active. If the output frequency exceeds that of the monitoring ramp, an latched safe torge off (LSTO) is generated. For applications with changing loads, an increase of P9680/P9880 or P9691/P9891 is recommended. A larger deviation of the output frequency from the reference is then acceptable. Note: A value of 99000 would deactivate the SBR monitoring, this value therefore is not allowed. Set P9880 accordingly. The ramping on selection of SLS or SS1 will however still follow the ramping time in P9681/P9881.

P9880 = … SI braking ramp delay Refer to P9680.

s 0.250 0.010 99.000

P9681 = … SI braking ramp-down time Defines the braking ramp-down time for the dafe braking ramp (SBR) in seconds. The ramp-down time is used for the SBR and the monitoring ramp. The total braking time Tx can be derived where fx is the current frequency according to the following formulas: a) For activation of the SLS: Tx = P9681 * (fx - P9690)/200 Hz b) For activation of SS1: Tx = P9681 * (fx - P9682)/200 Hz Note: In contrast to other ramping times (e.g. p1120, p1121), the SI braking ramp-down time is referred to 200 Hz and not to p1082. See formulas above.

Depending on the setting in P9692/P9892 the frequency of P9690/P9890 may also serve as a speed threshold instead of a setpoint (see P9692). Note: For applications with changing loads, an increase of P9680/P9880 or P9691/P9891 is recommended. If the "safely limited speed" (SLS) is selected while the output frequency is below the setpoint value, Bit 04 and Bit 05 will be set simultanously in r9772.

The tolerance defined by the difference P9691 to P9690 (or P9891 to P9890) is also used for the monitoring ramp when the SBR is active. For applications with changing loads it is recommended to increase P9691/P9891. Note: The value in P9691 needs to be larger than the value in P9690. This condition is checked when leaving the safety commissioning.

Commissioning 5.7 Commissioning with the MMC


5.7 Commissioning with the MMC

5.7.1 Parameter Download via MMC

Overview A G120 inverter can be parameterized by downloading a parameter set from the MMC to the inverter. The download can be performed as Manual Download Automatic Download A detailed download description can be found in the section "Upload and Download of Parameter Sets".

Note The file format for the MMC is FAT. Any other format, such as FAT32 or NTFS are not compatible with uploading and downloading parameter sets from the inverter. Formatting can be accomplished using the DOS command line as follows: C:\>format volume /FS:FAT - where volume has to be replaced by the name of the MMC drive, for example A Please keep in mind that formatting will delete all the contents of the MMC.



5.7.2 Series commissioning with MMC

Inserting and removing the MMC Before upload or download can be performed an MMC has to be fitted. How to fit and remove the MMC see the following figure:

Figure 5-5 Fitting and Removing the MMC

WARNING When inserting an MMC during operation Alarm A0564 appears if P8458 is set to 0. This is a hint that with P8458 = 0 no Automatic Download will be performed at startup. If the MMC is inserted to perform an upload this alarm can be quitted without any further action. If the MMC is inserted to perform an Automatic Download P8458 must be set accordingly.



Upload a parameter set with an MMC

Prerequisites To upload a parameter set the following important conditions must be fulfilled: An inverter with an appropriate parameter set is available (upload inverter). An MMC Type 6SL3254-0AM00-0AA0 is available. Supply voltage is active for the upload inverter. The upload inverter is in "Ready to Run"". The parameters are copied from RAM to EEPROM.

Procedure

Note During a parameter upload from the EEPROM to a MMC (e.g. for serial commissioning) the LEDs are flashing. If the Control Unit is in a faulty state, the fault will be displayed by the LEDs (SF on, RDY off).

Parameter Description (Parameter name and factory setting (if not variable) in bold) Setting Insert the MMC to the inverter - for the parameter set to be uploaded, perform the following

steps:

P0010 = 30 Commissioning parameter* 0: Ready 1: Quick commissioning 2: Inverter 30: Factory setting, parameter transfer 95: Safety commissioning (for CUs with fail-safe functions only)

P0804 = … Select Clone file 0: clone00.bin … 99: clone99.bin Note: Via P0804 the name of the clone file can be selected. Theoretically up to 100 (0 … 99) parameter sets can be stored on an MMC.

Note: Before uploading, the parameters will be copied from RAM to EEPROM.

P0802 = 2 Transfer data from EEPROM 0: Disabled 1: Start BOP Transfer 2: Start MMC Transfer

If the upload has been completed successfully, P0010 and P0802 will be set to 0 and the "RDY" LED is on. If the upload has failed, F0061 (MMC-PS not fitted) or F0051 (failure while accessing EEPROM) will be displayed, LED "SF" (red) is on. In this case insert an MMC and attempt another upload.



Parameter Description (Parameter name and factory setting (if not variable) in bold) Setting After a successful upload remove the MMC from the upload inverter to insert it into the

download inverter.

Manual Download of a parameter set with an MMC

Prerequisites Supply voltage is active for the download inverter The download inverter is in "Ready State". On the MMC the following folder structure must be available:

/USER/SINAMICS/DATA/clonexx.bin

Procedure

Note The following important conditions must be fulfilled when using the download procedure: • During the download the inverter will not react to any commands. • Once the download procedure has started, it cannot be interrupted. • After upload and download of parameters between differing Control Units, parameter

settings must be checked. • Parameter download from a different CU might fail with F0063 if parameters cannot be

downloaded (Check P949 for the (first) parameter number which cannot be downloaded).• If the download fails, the inverter reverts to the previous parameters from the EEPROM.

Parameter Description (Parameter name and factory setting (if not variable) in bold) Setting Insert the MMC to the download inverter and perform the Manual Download according the

flow chart.

P0010 = 30 Commissioning parameter* 0: Ready 1: Quick commissioning 2: Inverter 30: Factory setting, parameter transfer 95: Safety commissioning (for CUs with fail-safe functions only)

P0804 = … Select Clone file (for download) 0: clone00.bin … 99: clone99.bin

P0803 = 2 Transfer data to EEPROM 0: Disabled 1: Start BOP Transfer 2: Start MMC Transfer



Parameter Description (Parameter name and factory setting (if not variable) in bold) Setting If the download has been completed successfully, P0010 and P0803 will be set to 0 and the

"RDY" LED is on. If the upload has failed, F0061 (MMC-PS not fitted), F0062 (MMC-PS contents invalid) resp. F0063 (MMC-PS contents incompatible) or F0051 (failure while accessing EEPROM) will be displayed, LED "SF" (red) is on. In this case insert a proper MMC and attempt another download or perform a factory reset.

After a successful Manual Download the MMC can be removed from the inverter and inserted into the next download inverter. Then perform the download steps again until the series commissioning has been completed for all inverters.

Automatic Download The Automatic Download at start-up is controlled via P8458. With the Automatic Download all necessary parameters including the parameters regarding fail-safe functions are downloaded into the inverter.

Note MMC for "Automatic Download" For an Automatic Download always the file clone00.bin will be used. The user has to take care, that clone00.bin (saved as "clone00.bin" with STARTER on PC or via setting P0804 = 00 with the BOP) is available on the MMC, used for an automatic parameter download at start-up. Otherwise Automatic Download will not be processed.

Parameter P8458 controls the kind of the Automatic Download. The possible settings for P8458 and their functions are given below.

P8458 = 0: Automatic parameter download from the MMC is inhibited. P8458 = 1: Automatic parameter download from the MMC only once (at the next start-up

of the CU (default setting)). After the download P8458 is set to 0. P8458 = 2: Automatic parameter download from the MMC after each start-up of the

control unit.



Successful Automatic Download After a successful Automatic Download, F0395 will be displayed. Clearing F00395 is described in the section "Message F00395".

WARNING The user is responsible for ensuring that the parameters held in the CU are the correct parameters for their application.

Acceptance test On CUs with integrated fail-safe functions it is necessary to do an acceptance test (refer to the "Fail-safe functions" section in this manual). To clear F0395 on CUs with integrated fail-safe functions the following procedure has to be followed: P0010 = 30 P9761 = fail-safe password P7844 = 0 Carry out acceptance test

Automatic download fault If the Automatic Download process fails, the CU will return to the parameter set previously held in the EEPROM and the following fault codes are generated:

Table 5-10 Automatic download fault codes

Fault code Description F0061 Automatic download of parameters was not successful. (download file not found). F0063 Automatic download of parameters was not successful (download file not compatible). F0051 Failure while accessing EEPROM Clearing of these faults is described in the section "Faults and Alarms" of this manual.

In this case check, whether the MMC is defective or a parameter set clone00.bin is available or the parameter set is valid. For details refer to Parameter List. A valid parameter set means, it is not from a different type (e.g. CU20S DP and CU240S or fail-safe and standard CUs).

CAUTION Use of unscreened cables is possible, however we recommend the use of screened cables, in order to fulfill the EMC requirements for the CE marking and fail-safe products (CU240S DP-F).

Note

The cable from the encoder to the Encoder Module should be one complete length. TTL-encoder specific If the encoder type is a TTL differential and a long cable length is required (>50 m), DIP switches 5, 6, and 7 may be set to ON. If the encoder type is a TTL single-ended encoder, there will be a three wires for the ‘A’, 'B' and 'Z' Channels. HTL-encoder specific The terminating impedance which is selected using the DIP-switches must not be used in conjunction with an HTL encoder.

The encoder voltage is using the general I/O DIP switches 3 and 4. The following table shows the possible settings:

WARNING DIP switches 3 or 4 in ON position provide a supply voltage of 24 V to the encoder. Therefore it is not allowed to connect a TTL encoder to the inverter if one of the DIP switches, 3 or 4 are in ON position.



5.8.1 Parameterizing the Encoder Interface

Encoder parameterization To enable the encoder to function correctly with the inverter, the parameters in the table below, must be modified.

Table 5-13 Encoder parameters

Parameter Name Comment

P0400[3] Encoder type • 0: No encoder • 2 or12: Quadrature encoder (channel A + B) –

the term "quadrature" means two periodic functions separated by a quarter cycle or 90 degrees P0405 Encoder pulse types

Enables selection of various pulse types. Only bits 04 and 05 are used for the SINAMICS G120. See parameter list.

P0408[3] Pulses per revolution Specifies the number of encoder pulses per revolution. The manufacturer of the speed encoder specifies this value. 360, 500 or 1024 are values that are generally used. The encoder resolution (pulses per revolution p0408) which may be entered will be limited by the max. pulse frequency of the encoder circuits (f_max = 300 kHz). The following equation calculates the encoder frequency depending on the encoder resolution and the rotational speed (rpm). The encoder frequency has to be less than the max. pulse frequency:

P0410 Reverses internal direction sense

Setting P0410 =1 can be used to reverse the encoder signals instead of changing ENC_A and ENC_B wiring. 0: Encoder Normal Rotation 1: Encoder Reverse Rotation

P0491[3] Reaction on speed signal loss Selects reaction on loss of speed signal. Settings: 0: Trip with OFF2 1: Alarm and change to SLVC




P0492[3] Allowed speed difference This parameter defines the frequency threshold for the loss of the encoder signal (fault F0090). The threshold is used both for low as well as also high frequencies. 1. Signal loss at high frequencies:

Fault F0090 is output if the actual frequency and the frequency difference between two sampling periods (t_A) is greater than that specified in parameter p0492: (actual frequency f_act > p0492 and f(t_A2) - f(t_A1) > p0492)

Note A fixed delay time of 40 ms is stored in the frequency converter. Fault F0090 is only activated when the encoder signal is lost at a high frequency after this delay time has expired.

2. Signal loss at low frequencies: Fault F0090 is output if all of the conditions for case 1 or case 2 are simultaneously fulfilled:

Case 1 – actual frequency < p0492 – r0061 = 0 and the torque is limited – r0061 = 0 with setpoint frequency f_set > 0 for a time > p0494

Case 2 - actual frequency < p0492 - f(t_A2) < p0492 and a fault is detected in channel B Inter-dependency This parameter is updated after the motor starting time p0345 has been changed or the speed was optimized (p1960 = 1). Caution p0492 = 0 (no monitoring function): With p0492 = 0, the loss of the encoder signal at high frequency as well as at a low frequency is de-activated. As a result, the system does not monitor for the loss of the encoder signal. If the encoder signal loss is de-activated and the fault occurs, then the closed-loop motor control can become unstable

P0494[3] Delay speed loss reaction Used for low speed encoder loss detection. If the motor shaft speed is less than the value in P0492 then encoder loss is detected using a low speed encoder loss detection algorithm. This parameter selects the delay between loss of encoder at low speed and reaction to the encoder loss. (Default = Calculated from inertia, Range from 0 to 64.000s). Dependency: This parameter is updated when P0345 Motor start-up time is changed or when a speed-loop optimization is performed (P1960 = 1). Caution: When this delay is set to 0, then low speed encoder loss detection is disabled and low speed encoder loss cannot be detected (high speed encoder loss detection will still operate if P0492 > 0). If low speed encoder loss detection is disabled and encoder should be lost at low speed, then operation of motor may become unstable.

P1300 Control Mode 21: Closed loop speed control 23: Closed loop torque control



Table 5-14 Monitoring parameters


r0061 CO: Rotor speed Indicates the speed of the rotor. Used to check that the system is working correctly.

r0090 CO: Act. rotor angle Indicates the current angle of the rotor. This function is not available on single input channel encoders.

r0403 CO/BO: Encoder status word Displays status word of speed encoder in bit format: Bit 00 - Encoder active 0 = No 1 = Yes Bit 01 - Encoder fault 0 = No 1 = Yes Bit 02 - Signal OK 0 = No 1 = Yes Bit 03 - Encoder low speed loss 0 = No 1 = Yes

Bit 04 - Single edge measurement 0 = No 1 = Yes

CAUTION When commissioning the closed-loop Vector control with sensor (VC) the frequency inverter should first be operated with V/f control (p1300 = 0). When the motor is spinning and the speed encoder connected (activated using p0400), parameters r0061 and r0021 must match one another as far as the following quantities are concerned: • Sign • Absolute value (a deviation of a few percent is permitted) The closed-loop Vector control with sensor (encoder) (p1300 = 21 or 23) may only be activated if both conditions are fulfilled. Too short ramp times (P1120 and 1121) can cause F90, encoder feedback loss).

Note

If the encoder is incorrectly connected, incorrect values will be displayed in r0061, r0063, r0021 and r0022



5.8.2 Encoder Fault Codes

Description The Encoder Interface has only one fault code, – F0090. This condition occurs when the allowed frequency rate of change, set in P0492[3] is exceeded or when low speed encoder loss is detected.

Note The reason for the encoder loss will be given in the level 3 parameter r0949: r0949 = 1 means encoder loss of channel A or channel B, or encoder loss due to high speed (shaft speed > P0492). r0949 = 2 means encoder loss of channel A or channel A and channel B at low speed (shaft < P0492) r0949 = 7 means excessive flux variance which may cause motor instability - possible due to encoder loss.

CAUTION

Take care that signal loss on the inverted channels A and B is not observed by the inverter.

Remedial action on fault condition Should the encoder give a fault message F0090 the following remedial action should be performed: 1. Check that an encoder is fitted. If the encoder is not fitted, set P0400 = 0 and select

SLVC mode (P1300 = 20 or 22). 2. Check the connections between the encoder and the inverter. 3. Check the encoder is not faulty (select P1300 = 0 and run at a fixed speed then check the

encoder feedback signal using r0061). Check for correct magnitude and direction of speed.

4. Increase the encoder loss threshold in P0492. 5. Increase encoder low speed loss detection delay in P0494.

Commissioning 5.9 Parameters


5.9 Parameters

Overview of parameters The inverter is adapted to a particular application using the corresponding parameters. This means that each parameter is identified by a parameter number and specific attributes (e.g. monitoring parameter, write parameter, BICO attribute, group attribute etc.). Within any one particular inverter system, the parameter number is unique. Parameters can be accessed using the following operator units: BOP PC-based commissioning (start-up) tool STARTER. There are two main types of parameters; those that can be altered and those that are read-only.

Figure 5-6 Parameter types

5.9.1 Write parameters

Description Parameters which can be written into and displayed are indicated by the prefix "P". These parameters directly influence the behavior of a function. The value of this parameter is saved in non-volatile memory (EEPROM) as long as the appropriate option was selected (non-volatile data save). Otherwise, these values are saved in the volatile memory (RAM) of the processor, which are lost after power failure or power-off/power-on operations. Examples of the standard notation used throughout our manuals is given below.

Notation examples: P0970 parameter 970 P0748.1 parameter 748, bit 01 P0819[1] parameter 819 index 1 P0013[0 ... 19] parameter 13 with 20 indices (indices 0 to 19)



5.9.2 Monitoring parameters

Description Parameters which can only be monitored are indicated by the prefix "r". These parameters are used to display internal quantities, for example states and actual values.

Notation examples: r0002 monitoring parameter 2 r0052.3 monitoring parameter 52, bit 03 r0947[2] monitoring parameter 947 index 2 r0964[0 ... 4] monitoring parameter 964 with 5 indices (indices 0 to 4)

5.9.3 Parameter Attributes

Overview In the Parameter Manual, the header line of each parameter shows all the attributes and groups for that specific parameter. The figure below shows the details for parameter P0700 and r1515.

Figure 5-7 Description of attributes for parameter P0700

Figure 5-8 Description of attributes for parameter r1515

Index Using the index, a parameter (e.g. p0013[20]) is defined with several consecutive elements (in this case, 20). Each individual index is defined using a numerical value. When transferred to a parameter this means that an indexed parameter can have several values. The values are addressed using the parameter number including the index value (e.g. p0013[0], p0013[1], p0013[2], p0013[3], p0013[4], ...).



Indexed parameters are used, for example: Drive Data Sets (DDS) Command Data Sets (CDS) Sub functions.

BICO The following types of connectable parameters are available. A description of BICO technology is given in the section "BICO Technology".

Table 5-15 Parameter attributes - BICO

BICO Description BI Binector Input BO Binector Output CI Connector Input CO Connector Output CO/BO Connector Output/Binector Output

Access level The access level is controlled using parameter P0003. In this case, only those parameters are visible at the BOP, where the access level is less than or equal to the value assigned in parameter P0003. On the other hand, for STARTER, only access levels 0 and 3 are relevant. For example, parameters with access level 3 cannot be changed, if the appropriate access level has not been set. The following access levels are implemented in the inverters:

Table 5-16 Parameter attributes - access level

Access level Description 0 User-defined Parameter Manual (refer to P0013) 1 Standard access to the most frequently used parameters 2 Extended access, e.g. to inverter I/O functions 3 Expert access only for experienced users 4 Service access only for authorized service personnel – with password

protection.

Note In STARTER, all user parameters (access stage 3) are always displayed using the expert list – independent of the setting p0003 = 0, 1, 2 or 3. When changing parameters using STARTER, or via a high-level control system, parameter value changes always become immediately effective.



Can be changed "P" parameters can only be changed depending on the inverter state. The parameter value is not accepted if the instantaneous state is not listed in the parameter attribute "Can be changed". For instance, the quick commissioning parameter P0010 with the attribute "CT" can only be changed in quick commissioning "C" or ready "T" but not in operation "U".

Table 5-17 Parameter attributes - Can be changed

State Description C Quick commissioning U Operation (Drive running) T Drive ready to run

Data types The data type of a parameter defines the maximum possible value range. Five data types are used for the inverter. They either represent an unsigned integer value (U16, U32) or a floating-point value (float). The value range is frequently restricted by a minimum and maximum value (min, max) or using inverter/motor quantities.

Table 5-18 Parameter attributes - Data types

Data type Description U16 Unsigned, integer value with a size of 16 bits U32 Unsigned, integer value with a size of 32 bits I16 Signed integer 16-bit value I32 Signed integer 32-bit value Float A simple precise floating point value according to the IEEE standard format

max. value range: -3.39e+38 –+3.39e+38

Unit The values of parameters support the following units:

Table 5-19 Parameter attributes - Unit

Unit Description Unit Description - No dimension m/s Meters per second % Percentage Nm Newton meter A Ampere W Watt V Volt kW Kilowatt Ohm Ohm Hp Horse power us Microseconds kWh Kilowatt hours ms Milliseconds °C Degrees Celsius s Seconds m Meter Hz Hertz kg Kilograms kHz Kilohertz ° Degrees (angular degrees) 1/min Revolutions per minute [RPM]



Grouping The parameters are sub-divided into groups according to their functionality. This increases the transparency and allows a quicker and more efficient search for specific parameters. Furthermore, parameter P0004 can be used to control the specific group of parameters that are displayed on the BOP.

Table 5-20 Parameter attributes - Grouping

Active This attribute is only of importance in conjunction with an BOP. The "Yes" attribute indicates that this value is immediately accepted when it is changed. Especially parameters which are used for optimization functions have this property (e.g. constant voltage boost P1310 or filter time constants). On the other hand, for parameters with the attribute "First confirm", the value is only accepted after first pressing the key . These include, for example, parameters where the parameter value can have different settings/meanings (e.g. selecting the frequency setpoint source P1000).

Table 5-21 Parameter attributes - Active

Active Description Yes The value becomes valid immediately. First confirm The value becomes valid after pressing

Note Parameter values that are changed using STARTER or a higher-level control do not have to be acknowledged.



Quick commissioning This parameter attribute identifies as to whether the parameter is included in the quick commissioning (QC) (P0010 = 1).

Table 5-22 Parameter attributes - Quick commissioning

QC Description No The parameter is not included in the quick commissioning Yes The parameter is included in the quick commissioning

Value range The value range, which is first specified by the data type, is restricted by minimum and maximum values depending on the quantities of the inverter/motor. The values min and max are permanently saved in the inverter and cannot be changed by the user. To support commissioning each write parameter has a default value called factory setting.

Commissioning 5.10 Start-up and Swap Behavior of the Inverter


5.10 Start-up and Swap Behavior of the Inverter

Overview When starting-up the inverter checks, whether an MMC is plugged in or not. If it is plugged and no swap has been taken place the start-up runs according the "Normal start-up behavior". If a component (CU or PM) has been replaced, this is called a swap and the start-up will be performed according the "Swap behavior" of the inverter.

5.10.1 Normal Start-up Behavior of the Inverter

Description A normal start-up is a start-up after a power-cycle or a black-out. It can be performed with or without MMC.

Normal start-up behavior without MMC After a power-cycle or a black-out the inverter reads the parameters from EEPROM to RAM.

Normal start-up behavior with MMC The CU detects automatically whether an MMC is present. The start-up behavior is controlled using P8458 as follows:

P8458 = 0: No automatic parameter download from the MMC. P8458 = 1: Automatic parameter download from the MMC only once (at the next start-up

of the CU (default setting)). After the download P8458 is set to 0, to prohibit any further automatic download of parameters.

P8458 = 2: Automatic parameter download from the MMC (if present) after each start-up of the control unit.

Once the download has been finished, the MMC can be withdrawn. If no MMC is plugged in, the inverter will start-up with the parameters stored in the EEPROM without an alarm or fault message, even if P8458 is set to 1 or 2.

Note MMC for "automatic download" For an automatic download always the file clone00.bin will be used. The user has to take care, that clone00.bin (saved as "clone00.bin" with STARTER via PC or via setting P0804 = 00 with the BOP) is available on the MMC under /USER/SINAMICS/DATA/clone00.bin, used for an automatic parameter download at start-up. If clone00.bin does not exist drive will fail with F0061.



Successful automatic download After a successful automatic download, F0395 will be displayed. In case of a standard CU a confirmation is necessary. In the case of CUs with fail-safe functions, an acceptance test must be performed. Confirmation On standard CUs the current parameter set needs to be checked and its correctness confirmed by clearing F0395. This can be done via: Digital input or PLC signal (depends on the settings of P0700) Setting P7844 = 0. Via the key on the BOP

WARNING

The user is responsible for ensuring that the parameters held in the CU are the correct parameters for their application.

Acceptance test On CUs with fail-safe functions it is necessary to do an acceptance test (refer to the "Fail-safe functions" section in this manual). To clear F0395 on CUs with fail-safe functions the following procedure has to be followed: P0010 = 30 P9761 = safety password P7844 = 0 Carry out acceptance test

Download Aborted Another way of clearing F00395 is to set P7844 = 2 (only possible if a MMC clone has been performed). In this case all new parameters from MMC are discarded and the inverter reloads its parameters from the EEPROM.

WARNING

By setting P7844 = 2 the user is responsible for ensuring that the parameters held in the EEPROM are the correct parameters for their application.

In case of standard CUs: – P7844 = 2 – F00395 is acknowledged automatically

In the case of CUs with fail-safe functions, the following procedure is necessary: – P0010 = 95 – P9761 = safety password – P7844 = 2 – Carry out acceptance test



Automatic download fault If the automatic download process fails, the CU will return to the parameter set previously held in the EEPROM and one of the following fault codes will be generated:

Table 5-25 Automatic download fault codes

Fault code Description F0061 Automatic download of parameters was not successful. F0063 Automatic download of parameters was not successful (e.g. wrong CU).

In this case check, whether the MMC is defective, a parameter set clone00.bin is available, or the parameter set is valid.

NOTICE After upload and download of parameters between differing Control Units, the parameter settings must be checked. Parameter download from a different CU might fail with F0063 if parameters cannot be downloaded (Check r0949 for the (first) parameter number which cannot be downloaded). If F0061 or F0063 occurs during startup it cannot be cleared except via a power cycle.

5.10.2 Swap Behavior of the Inverter

Overview This section describes the possibilities to exchange inverter components, power modules or control units, and the necessary actions, depending on the swap type. The following swaps are allowed: CU swap (neither PM nor CU powered) PM swap (neither PM nor CU powered) PM swap (CU externally powered)

Note A swap is indicated by a F00395. A download fault during swap will be indicated by F00061 or F00063. If F00061 or F00063 occurs during startup it cannot be cleared except via a power cycle.



CU swap, PM swap (whether PM nor CU powered) Constraints: MMC with valid Parameter set plugged Swap after power on detected, Parameter MMC -> RAM, inverter runs into F00395 Confirmation for standard CU or acceptance test in case of fail-safe CU required After acknowledge of F00395 data are transferred automatically from RAM to EEPROM

(except P7844 = 2) constraints: no MMC Swap after power on detected, Parameter EEPROM -> RAM, inverter runs into F00395 Commissioning recommended - otherwise inverter runs with parameter settings from

EEPROM Confirmation for standard CU or acceptance test in case of fail-safe CU required

PM swap (CU externally powered) Constraints: MMC with valid Parameter set plugged Swap detected, Parameter MMC -> RAM, inverter runs into F00395 Confirmation for standard CU or acceptance test in case of fail-safe CU required After acknowledge of F00395 data are transferred automatically from RAM to EEPROM

(except P7844 = 2) Constraints: no MMC Swap detected, Parameter EEPROM -> RAM, inverter runs into F00395 If the parameters, already held in the EEPROM are ok there is no commissioning

necessary. Confirmation for standard CU or acceptance test in case of fail-safe CU required

Note After a PM swap without MMC the parameter settings only stored in RAM will be lost



Successful swap After a successful swap, F00395 will be displayed. In case of a standard CU a confirmation is necessary. In the case of CUs with fail-safe functions, an acceptance test must be performed. Confirmation On standard CUs the current parameter set needs to be checked and its correctness confirmed by clearing F00395. This can be done via: Digital input or PLC signal (depends on the settings of P0700) Setting P7844 = 0. Via the key on the BOP

WARNING

The user is responsible for ensuring that the parameters held in the CU are the correct parameters for their application.

Acceptance test On CUs with fail-safe functions it is necessary to do an acceptance test (refer to the "Fail-safe functions" section in this manual). To clear F00395 on CUs with fail-safe functions the following procedure has to be followed: P0010 = 30 P9761 = safety password P7844 = 0 Carry out acceptance test

Download Aborted Another way of clearing F00395 is to set P7844 = 2 (only possible if a MMC clone has been performed). In this case all new parameters from MMC are discarded and the inverter reloads its parameters from the EEPROM.

WARNING

By setting P7844 = 2 the user is responsible for ensuring that the parameters held in the EEPROM are the correct parameters for their application.

In case of standard CUs: – P7844 = 2 – F00395 is acknowledged automatically

In the case of CUs with fail-safe functions, the following procedure is necessary: – P0010 = 95 – P9761 = safety password – P7844 = 2 – Carry out acceptance test



Swap fault A swap fault is indicated if the automatic download fails. In this case, the CU will return to the parameter set previously held in the EEPROM and F00395 as well as one of F00061, F00062 and F00063 will be generated. On standard CUs the current parameter set needs to be checked and its correctness confirmed by clearing F00395. This can be done via: Digital input or PLC signal (depends on the settings of P0700) Setting P7844 = 0. Via the key on the BOP In the next step F00061 / F00062 or F00063 has to be cleared via power cycle.

Note F00395 cannot be cleared via power cycle. F00061, F00062 and F00063 can only be cleared via power cycle.

In case of a swap fault check, whether the MMC is defective or a parameter set clone00.bin is available or the parameter set is valid. A valid parameter set means, it is not from a different type (e. g. CU240S DP and CU240S or fail-safe and standard CUs)

Rules regarding swap and hot swap There are a number of scenarios where a swap or hot swap can take place, each with their own unique set of conditions that must be observed.

DANGER Do not attempt to hot swap a power module (PM) Before attempting to swap a PM it must be fully powered-down. Any attempt to swap-out a PM when power is still applied could result in death of personnel and severe damage to property and equipment.

WARNING

Swap restrictions Before performing a swap take care of the following: • It is the responsibility of the user to ensure that only CUs of the same type are swapped • It is the responsibility of the user to ensure that the MMC contains the correct parameter

set • It is the responsibility of the user to ensure that only PMs of the same type and power

rating are swapped. • It is the responsibility of the user to ensure that the application is in a safe state before

any swap of equipment is performed.



Swapping a CU The following procedure is given as a guide to perform a swap of a CU.

CAUTION Data set compatibility To ensure complete data set compatibility, it is recommended to perform an upload of the parameter set from the CU to a new MMC prior to swapping the CU.

Before performing a CU swap take care of the following: 1. The PM is powered-down and disconnected. 2. Wait 5 minutes to allow the unit to discharge after switching off the line supply. 3. Remove the two-part terminals that are actually wired on the CU. 4. Remove the MMC. 5. Remove the CU from the PM. Before switching on power supply to the inverter take care of that: 1. Fit the new CU to the PM. 2. Reconnect the two-part terminals to the CU. 3. Insert the MMC into the MMC-slot of the CU.

Swapping the PM

CAUTION To ensure complete data set compatibility, make sure that all parameters are stored in the EEPROM of the Control Unit (see P0014 or P0971) prior to swapping the PM).

Before performing a PM swap take care of the following: 1. The PM is powered-down and disconnected. 2. Wait 5 minutes to allow the unit to discharge after switching off the line supply. Before switching on Power supply take care of that: 1. The new PM is properly installed and connected. 2. The CU is fitted back on the PM.


Communication 66.1 PROFIdrive Profile V4.0

6.1.1 Use Data Structure as Defined in PROFIdrive Profile 4.0

Introduction The SINAMICS G120 range of inverters can be controlled through the cyclical PROFIBUS DP channel or the acyclic DPV1 channel. The structure of use data for the cyclic/acyclic channel for is defined in the PROFIdrive Profile, version 4.0. The PROFIdrive profile defines the inverters, the use data structure with which a master can access the inverters (slaves) using the cyclic or acyclic data communication method.

Note PROFIdrive for drive technology is standardized and described in the following document: References: /P5/ PROFIdrive Profile Drive Technology

Telegram data structure The use data structure for cyclical data traffic is divided into two areas which can be transmitted in each telegram: Process data area (PZD)

Process data includes control words (status information) and setpoints (actual values). Process data are transmitted in the process data area. The transferred process data do not take effect until the bits used in the control words, setpoints, status words and actual values have been routed in the inverter.

Parameter channel This area is reserved for reading/writing parameter values. This telegram section is used to monitor and/or change any parameter in the inverter. For further information to the parameter channel, refer the Function Manual.

6.1.2 Data Structure of the Parameter Channel

Description The PROFIdrive profile V4.0 defines for the inverters, the use data structure with which a master can access the inverters (slaves). The parameter channel telegram section can be used to monitor and/or change any parameter in the inverter.

Parameter channel Using the parameter channel process data can be processed and monitored (write/read) as described below. The parameter channel includes always 4 words.

Figure 6-1 Structure of the parameter channel in the telegram structure



Parameter identifier (PKE), 1st word The parameter identifier (PKE) is always a 16-bit value.

Figure 6-2 PKE structure

Bits 0 to 10 (PNU) contain the remainder of the parameter number (value range 1 to 61999).

For parameter numbers ≥ 2000 it is necessary to add an offset which is defined with the high byte bits (acyclic) or the low byte bits (cyclic) of IND. Bit 11 (SPM) is reserved and always = 0. Bits 12 to 15 (AK) contain the request or the response identifier. The meaning of the request identifier for request telegrams (master → inverter) is shown in the table below.

The array subindex is an 8-bit value which is in acyclical data exchange mode transferred in the low-order byte (bits 0 to 7) of the parameter index (IND).

The parameter page selection task for additional parameters is performed in this case by the high-order byte (bits 8 to 15) of the parameter index. This structure conforms to the USS specification. Example: Coding for parameter no. in PKE and IND for "P2016, Index 3".

Parameter value (PWE) 3rd and 4th word In case of PROFIBUS or PROFINET communication the parameter value (PWE) is always transmitted as a double word (32-bit). Only one parameter value at a time can be transferred in a telegram. A 32-bit parameter value comprises PWE1 (high-order word, 3rd word) and PWE2 (low-order word, 4th word). A 16-bit parameter value is transferred in PWE2 (low-order word, 4th word). PWE1 (high-order word, 3rd word) must be set to 0 on the PROFIBUS-DP master in this case.

Note In case of communication via USS, you can configure the word length in P2013. For details, refer the section "Communication via USS".

Rules for processing requests/responses A request or a response can only ever refer to one parameter. The master must repeat a request continuously until it has received the appropriate

response. The master detects the response to a request it has sent by

– evaluating the response identifier, – evaluating the parameter number PNU, – evaluating the parameter index IND if necessary, or – evaluating the parameter value PWE if necessary.

The complete request must be sent in one telegram. Request telegrams cannot be split. The same applies to responses.

In the case of response telegrams which contain parameter values, the drive always returns the current parameter value when repeating response telegrams.

If no information needs to be fetched from the parameter channel interface in cyclical operation (only PZD data are relevant), then the "No request" request telegram must be issued.

If VIK/NAMUR telegram is selected with P0922 = 20, the parameter P2038 "Selection of actual profile" will be set to VIK/NAMUR automatically. It is also necessary to set the ident number (GSD) via parameter P2042: SIMATIC Object Manager (Slave-OM)

For drives configured with SIMATIC Object Manager (Slave-OM) parameter P2042 has to be set to 0 (default).

VIK/NAMUR GSD (Device Data File) For all other configurations the setting of parameter P2042 must be changed to 1 (NAMUR). That means that the VIK/NAMUR ID of the PROFIBUS Nutzerorganisation (PNO) will be send to the PLC.

Note If changing PROFIBUS standard telegrams to VIK/NAMUR telegram or back (parameters: P0922, P2038 and P2042) the drive ID is changed. A power cycle is necessary for the Control Unit CU240S to take the changed drive ID effective. To change back from VIK/NAMUR to Standard telegrams it is necessary to set P0922 = 999 (Free BICO connection) and then reset P2038 and P2042 to PROFIdrive Profile. If P0922 = 999, it keeps the actual BICO connection parameters but now BICO parameters can be changed.



6.2.4 PROFIsafe Telegram Structure

Description The fail-safe functions can be triggered via the fail-safe digital inputs FDI0 and FDI1 or via PROFIsafe signals (see P9603 and 9803). To use PROFIsafe for triggering the fail-safe functions the G120 GSD file must be installed in the control system e.g. SIMATIC S7. Input and output address, 6 byte each (input and otuput address are identical)

• Byte 0 (process data 0), Bit 0: STO 0 = selected 1 not selected • Byte 0 (process data 0), Bit 1: SS1 0 = selected 1 not selected • Byte 1 (process data 1), Bit 0: SLS 0 = selected 1 not selected

2090:14 15 1 Depends on the protocol

On the SINAMICS G120 it is possible, using the function local/remote control, to change between the command data set (CDS) 0 and 1 of the control word 1 bit 15. This results in a switching of the command data sets. The command data set 0 is active in local operation and the command data set 1 for remote operation. Now in both command data sets the application-specific parameters for the command and target value sources can be set. *Note: In PROFIdrive Profile P0810 = 2090:15 must be set manually.

DDS1: P0820 = 2091.15

CDS1: P0810 = 2090:15*



An example In the remote control operating mode the commands and target values come from a superior control system to the inverter by means of a PROFIBUS. By switching to local operation, the command and target value source is switched and operation is now performed locally on the system by means of digital inputs and the analog target values. Local operation = Command data set 0: In this case the command code of the terminal strip P0700 Index 0 = 2 and the frequency target value is the analog target value P1000 Index 0 = 2. Remote operation = Command data set 1: In this case the command code corresponds with the control word (word 0) received from the PROFIBUS P0700 Index 1 = 6 and the frequency target value corresponds with the control word 1 received from the PROFIBUS P1000 Index 1 = 6.

Communication 6.3 Acyclic Communication


6.3 Acyclic Communication

Extended PROFIBUS DP functionality (DPV1) The PROFIBUS DP extensions DPV1 include the definition of an acyclic data exchange which can take place in parallel to cyclic data transmissions. Acyclic data transfer mode allows: Large quantities of use data (up to 240 bytes) to be exchanged Simultaneous accessing by other PROFIBUS masters (class 2 master, e.g. start-up tool).

Conversion of extended PROFIBUS DP functionality The different masters, or different modes of data exchange, are represented by appropriate channels in the SINAMICS G120 range of inverters: Acyclic data exchange with the same class 1 master use of DPV1 functions READ and

WRITE. The content of the transferred data block (DS) corresponds in this case to the structure of the acyclic parameter channel according to PROFIdrive Profile, version 4.0 (http://www.profibus.com/organization.html) (with data block 47 (DS47)).

Acyclic data exchange using a SIEMENS start-up tool (class 2 master) (e.g. STARTER). The start-up tool can acyclically access parameter and process data in the inverter.

Acyclic data exchange with a SIMATIC HMI (second class 2 master). The SIMATIC HMI can acyclically access parameters in the inverter.

Instead of a SIEMENS start-up tool or SIMATIC HMI, an external master (class 2 master) as defined in the acyclic parameter channel according to PROFIdrive Profile version 4.0 (with DS47) can access the inverter.

The order numbers of all hardware components can be read out by an acyclic channel

6.3.1 DPV1 Parameter Channel (DS47)

Properties of the DPV1 parameter channel One 16-bit address each for parameter number and subindex. Concurrent access by several PROFIBUS masters (class 2 master, e.g. commissioning

tool). Transfer of different parameters in one access (multiple parameter request). Transfer of complete arrays or part of an array possible. Only one parameter request is processed at a time (no pipelining). A parameter request/response must fit into a data set (max. 240 bytes). The task or response header are use data.



Structure of parameter request and parameter response A parameter request consists of three segments: Request header

ID for the request and number of parameters which are accessed. Parameter address

Addressing of a parameter. If several parameters are accessed, there are correspondingly many parameter addresses. The parameter address appears only in the request, not in the response.

Parameter value Per addressed parameter, there is a segment for the parameter values. Depending on the request ID, parameter values appear only either in the request or in the reply.

6.4 Communication via PROFIBUS

6.4.1 General Information About PROFIBUS for SINAMICS

General information PROFIBUS is an open international field bus standard for a wide range of production and process automation applications. The following standards ensure open, multi-vendor systems: International standard EN 50170 International standard IEC 61158 PROFIBUS is optimized for high-speed, time-critical data communication at field level.

Note PROFIBUS for drive technology is standardized and described in the following document: Reference: /P5/ PROFIdrive Profile Drive Technology

CAUTION Before synchronizing to the isochronous PROFIBUS, all of the pulses of the drive objects must be inhibited - also for those drives that are not controlled via PROFIBUS.

Technical data To display information about the current operating state of the inverter and the communication link, the PROFIBUS DP has three LEDs on the Standard Control Unit and seven on the Control Unit with fail-safe functions. Its voltage is supplied through the inverter system connector. The PROFIBUS DP is connected to the PROFIBUS system using a 9-pin sub-D type socket according to the PROFIBUS standard. All connections to this interface are short-circuit-proof and isolated. The PROFIBUS DP supports baud rates of 9.6 kbaud to 12 Mbaud.



6.4.2 Communication Settings PROFBUS DP

Setting the PROFIBUS DP address Prior to using the PROFIBUS DP interface, the address of the node (inverter) must be set. There are two methods for setting the PROFIBUS DP address: Using the seven DIP-switches on the Control Unit Using parameter "P0918"

CAUTION

If changing the PROFIBUS DP address, a power cycle is necessary for the Control Unit CU240S to make the new PROFIBUS DP address setting effective. The restart must be initiated by switching the power off and then on again, irrespective of whether the interface is supplied from the inverter mains supply or its own, separate 24 V power supply connection.

Figure 6-7 PROFIBUS DP address DIP-switches



The PROFIBUS DP address can be set between 1 and 125, as shown in the table below.

Table 6-26 Example address for the PROFIBUS DP interface

DIP switch 1 2 3 4 5 6 7 Add to address 1 2 4 8 16 32 64 Example 1: Address = 3 = 1 + 2

Example 2: Address = 88 = 8 + 16 + 64

The valid address range is shown in the table below:

Table 6-27 PROFIBUS DP address

DIP switch settings

Meaning

0 PROFIBUS DP address is determined by P0918 1 … 125 Valid PROFIBUS DP address 126, 127 Invalid PROFIBUS DP address

PROFIBUS DP parameters The following parameters must be set to start-up the PROFIBUS DP interface:

Table 6-28 PROFIBUS DP parameters

Parameter Content P0918 PROFIBUS address P0700 Selection of command source P0922 Selection of PROFIBUS standard telegram P1000 Selection of frequency setpoint P2038 Selection of communication profile P2042 Selection of the ident number (native or NAMUR) send to PLC r2050 Process data setpoint source (BICO) P2051 Process data actual values (BICO) P2041 Communication board functions P2040 Process data telegram failure time P0927 Modification source for parameters r2054 Communication board diagnostics



P0918 PROFIBUS Address If address 0 is set on the DIP-switches of the Control Unit (default setting), then the

PROFIBUS DP address can be changed in parameter P0918. Valid settings are 1 to 125 (default = 3).

DIP-switch address settings have priority to P0918 settings. That means if a valid PROFIBUS DP address is set via DIP-switches, the settings of P0918 will be ignored. In this case, the parameter displays the PROFIBUS DP address as set on the DIP-switches.

P0700 and P1000 selection of command and setpoint source Command and setpoint source can be quickly selected via P0700 and P1000. P0922 Selection of PROFIBUS standard telegram For failure-free operation, you must select the correct type of telegram. For details, refer

to section "Cyclic Communication" of this manual or the Parameter Manual. r2050 and P2051 BICO Much greater flexibility is afforded by the interconnection of process data using

binectors/connectors. Detailed connection of setpoints and actual values to and from the PROFIBUS DP

interface is parameterized in r2050 and P2051. The following table shows the parameters specific to the PROFIBUS DP interface relating

to the connection of process data:

P2041 PROFIBUS DP functions A number of advanced property settings for the PROFIBUS DP interface can be accomplished using the indexed parameter P2041. For most applications, however, the defaults values are adequate (value = 0). The following table shows the property setting options.

0: Standard diagnostics

Process data monitoring Two parameters determine how process data are monitored: Process data monitoring function on the PROFIBUS DP interface (standard slave

function according to PROFIBUS) The process data monitoring function on the PROFIBUS DP interface is normally activated. It can be deactivated by means of the PROFIBUS master configuring tool.

Monitoring of the telegram failure time in the converter with parameter P2040 Parameter P2040 defines the time after which a fault will be generated (F0070) if no telegram is received through the PROFIBUS DP interface. – P2040 = 0 means: No monitoring – P2040 > 0 means: The time in milliseconds after which a fault condition will be

generated if a setpoint telegram has not been received.

CAUTION

The process data monitoring function should not be deactivated! If the monitoring function is deactivated, the inverter will not recognize a PROFIBUS DP communication failure and continue to operate with possibly wrong commands and setpoints.

F0070 is activated if no new setpoints are received by the PROFIBUS DP interface within the telegram failure period.

CAUTION Shutdown on faults can only take place if both monitoring functions are activated!

When the PROFIBUS DP interface is in operation, parameter P2040 should also be set to a value of > 0. The process data monitoring function is thus activated/deactivated solely using the PROFIBUS process data monitoring function. The monitoring time then corresponds to the process data monitoring time setting plus the time set in P2040.

Note Process data whose complete control word (PZD1) is set to zero are not transferred from the PROFIBUS DP interface to the inverter. Result: Alarm A0703 and possibly fault F0070.

6.4.3 Configuration Example with SIMATIC S7

Installing a G120 GSD file The inverter can be integrated into a higher level control device, e.g. SIMATIC S7 via the GSD file. It can be downloaded from the internet via: http://support.automation.siemens.com/WW/view/de/23450835 The GSD must be installed in the engineering software of the higher level control device. The following example shows how to install the GSD in HW Config of SIMATIC S7.

Figure 6-8 Installing the G120 GSD in HW config SIMATIC S7

Install the *.GS* file in the desired language (english, french, german, italian or spanish) from the folder where you have stored the data. The following figure shows how to integrate an inverter with integrated fail-safe functions and a SIEMENS standard telegram in a SIMATIC S7. The inverter gives the possibility to work with different kind of telegrams. The selection of the telegram is made by the parameter P0922 during drive commissioning. The received telegram is in r2050[8] and transmit telegram is decided by parameter P2051[8].

Note Ensure that the PROFIsafe Module is installed in slot 1 (as shown in the figure above). In the following slot a SIEMENS telegram or a standard telegram can be installed.

Communication 6.5 Communication via PROFINET


6.5 Communication via PROFINET

General information PROFINET IO is an open Industrial Ethernet standard for a wide range of production and process automation applications. PROFINET IO is based on Industrial Ethernet and observes TCP/IP and IT standards. The following standards ensure open, multi-vendor systems: International standard IEC 61158 PROFINET IO is optimized for high-speed, time-critical data communication at field level.

PROFINET Within the framework of Totally Integrated Automation (TIA), PROFINET represents a consequent enhancement of the following communication systems: PROFIBUS DP

The established field bus Industrial Ethernet

The communication bus for the cell level Experience gained from both systems was and is being integrated into PROFINET. As an Ethernet-based automation standard defined by PROFIBUS International (PROFIBUS user organization), PROFINET is a manufacturer-independent communication and engineering model. SINAMICS G120 with CU240S PN is an IO device in the sense of PROFINET. With CU240S PN, communications is established via PROFINET IO with RT.

Note PROFINET for drive technology is standardized and described in the following document: References: /P5/ PROFIdrive Profile Drive Technology PROFINET System Description, Order no. 6ES7398-8FA10-8BA0, 6ES7151-1AA10-8AA0



6.5.1 Real-Time (RT) Communication

Real-time communication If supervisors are involved in communication, this can result in excessively long runtimes for the production automation system. When communicating time-critical IO use data, PROFINET therefore uses its own real time channel, rather than TCP/IP.

Definition: Real Time (RT) and determinism Real time means that a system processes external events over a defined period. Determinism means that a system responds in a predictable manner (deterministically). In industrial networks, both of these requirements are important. PROFINET meets these requirements. PROFINET is implemented as a deterministic real time network as follows: Transmission of time-critical data takes place at guaranteed time intervals. To achieve

this, PROFINET provides an optimized communication channel for real time communication: Real Time (RT).

An exact prediction of the time at which the data transfer takes place is possible. Problem-free communication using other standard protocols is guaranteed within the

same network.

6.5.2 Addresses

MAC address Each PROFINET device is assigned a worldwide unique device identifier in the factory. This 6-byte long device identifier is the MAC address. You can see the MAC address with support of commissioning tools as PST, STEP 7 or STARTER. The MAC address is divided up as follows: 3 bytes manufacturer's ID and 3 bytes device identifier (consecutive number). The MAC address is indicated on the rating plate of the Control Unit. The MAC address is stored in the parameter r61002. Example for a MAC address: 08-00-06-6B-80-C0

IP address The IP address is unique within the network. A PROFINET device also requires an IP address to be addressed as a node on Industrial Ethernet. The IP address is made up of 4 decimal numbers with a range of values from 0 through 255. The digit blocks are separated by points, e g. 192.188.1.1. The IP address is made up of the following: The address of the (sub-) network The address of the node (generally called the host or network node)



IP address assignment The TCP/IP protocol is a prerequisite for establishing a connection and parameterization. This is the reason that an IP address is required. The IP addresses of IO devices can be assigned by the IO controller and have always the same sub-network mask as the IO controller. The IP addresses can be consecutively assigned from the IP address of the IO controller. If the IP address is set by the IO controller, it is saved in a volatile fashion. Furthermore, you can change the IP address manually. In this case, the IP address is saved in non-volatile fashion. If the IP address is to be stored in a non-volatile memory, the address must be assigned using the Primary Setup Tool (PST). This can also be carried out in HW Config in STEP 7, where the function is called "Edit Ethernet node".

Note If the network is part of an existing Ethernet company network, obtain the information from your network administrator (IP address, sub-network mask and a router that is possibly being used.)

Sub-network mask The bits set in the sub-network define the part of the IP address that contains the address of the (sub-) network. The subnet mask provides a filter function for the Ethernet telegrams. The following generally applies: The network address is obtained by an AND operation on the IP address and sub-

network mask The node address is obtained by an AND NOT operation on the IP address and sub-

network mask.

Example of the sub-network mask Sub-network mask: 255.255.0.0 (decimal) = 11111111.11111111.00000000.00000000 (binary) IP address: 140.80.0.2 significance: The first 2 bytes of the IP address decide the sub-network - in other words 140.80. The last two bytes address the node - in other words 0.2.

Default Gateway The default gateway enables communication via an internal server.



Module ID A drive unit can be represented by a slot model. The slot model of the CU240S PN provides modules and sub-modules. The module-ID is the ID of a slot module or slot sub-module in this model. The module ID has four digits and is assigned by the system. The slot model of the CU240S PN provides two main module ID: Module ID of slot 0, device access point (DAP)

This module ID is used as a representative of the device. This module ID does not provide access to the drive parameters.

Module ID of slot 1, parameter access point (PAP) This module ID provides access to the following: – All drive parameters via the parameter access point – The cyclic data via defined telegrams

Device name At delivery state, an IO device does not have a device name. You assign a device name with the IO supervisor. Then, the IO device can be addressed by an IO controller. The device name is used to transfer of project engineering data (including the IP address) during startup.

Note The device name must be saved in a non-volatile fashion either using the Primary Setup Tool (PST) or using HW Config from STEP 7.

Device-ID Each PROFINET device has a specific device ID that is issued by device manufacturer. The device ID provides replacing an IO device without configuring in STEP 7. The device-ID for SINAMICS G120 indicates the following table:

Vendor ID Device ID

Class of device Device familiy 002A 05 02

(=Siemens AG) (=Drives) (=SINAMICS G120)

Replacing Control Unit CU240S PN (IO Device) If the IP address and device name are stored in a non-volatile memory, this data are also forwarded by the Micro Memory Card (MMC) of the Control Unit. If an IO device must be completely replaced due to a device or sub-module defect, the Control Unit automatically assigns parameters and configures the new device or sub-module. Following this, cyclic exchange of use data is restarted. The MMC allows module exchange without an IO supervisor when a fault occurs in a PROFINET device.



Default router If data needs to be forwarded by means of TCP/IP to a partner located outside the sub-network, this is carried out via the default router. In the properties dialog in STEP 7 (Properties of Ethernet interface > Parameters > Network transfer), the default router is described as the router. STEP 7 assigns the local IP address to the default router.

6.5.3 PROFINET Communication Parameters

PROFINET parameters The following parameters must be set to start-up the PROFINET interface:

Table 6-33 PROFINET parameters

P0700 and P1000 selection of command and setpoint source Command and setpoint source can be quickly selected via P0700 and P1000. r8850 and P8851 BICO Much greater flexibility is afforded by the interconnection of process data using

binectors/connectors. Detailed connection of setpoints and actual values to and from the PROFINET interface

is parameterized in r8850 and P8851. The following table shows the parameters specific to the PROFINET interface relating to

the connection of process data:

0: Standard diagnostics

Process data monitoring The process data are monitored according to the following parameter: P8840 Fieldbus Off-time.

If no telegram is received through the PROFINET interface, the fault F0070 will be generated. If no telegram is received , Parameter P8840 defines the period of time till the fault message is generated. – P8840 = 0 means: No monitoring – P8840 > 0 means: The period of time in milliseconds

CAUTION

Do not deactivate the process data monitoring function! If the monitoring function is deactivated, the inverter will not recognize a PROFINET communication failure and continue to operate with possibly wrong commands and setpoints.

F0070 is activated if no new setpoints are received by the PROFINET interface within the telegram failure period.



CAUTION Shutdown on faults can only take place if both monitoring functions are activated!

When the PROFINET interface is in operation, parameter P8840 should also be set to a value of > 0. The process data monitoring function is thus activated/deactivated solely using the PROFIBUS process data monitoring function. The monitoring time then corresponds to the process data monitoring time setting plus the time set in P8840.

Note Process data whose complete control word (PZD1) is set to zero are not transferred from the PROFINET interface to the inverter. Result: Alarm A0703 and possibly fault F0070.

Description Using the Universal Serial Interface (USS) protocol, a user can establish a serial point-to-point data link (RS232 interface) and a serial bus data link between a higher-level master system and several slave systems (RS485 interface). Master systems can be e.g. PLCs (e.g. SIMATIC S7-200) or PCs. The inverters are always the slaves on the bus system. The USS protocol allows the user to implement both automation tasks with cyclical telegram traffic (a fixed telegram length is necessary) as well as visualization tasks. In this case, the protocol with variable telegram length is advantageous, as texts and parameter descriptions can be transferred in one telegram without chopping up the information. With the RS232 interface only direct connections (point-to-point) are possible with cable lengths of 2 m … 5 m typically. This is typically used to commission a drive where the commissioning software (e.g. STARTER) runs on a PC. For this configuration the optional PC Connection Kit is available. With the RS485 interface simple and cheap networks can be constructed. The topology must be that of a line with the first and last devices of the line terminated with termination resistors.

6.6.3 Structure of a USS Telegram

Description The following figure shows the structure of a typical USS telegram. It consists of a start delay, 4 framing bytes (STX, LGE, ADR and BCC) and the n use data.

STX LGE ADR 1 . 2 . n . BCC : : :

n use data Figure 6-18 Structure of USS telegram

A typical frame consists of: STX 1 Byte LGE 1 Byte ADR 1 Byte BCC 1 Byte PKW 8 Bytes (4 Words: PKE + IND + PWE1 + PWE2) PZD 4 Bytes (2 Words: PZD1 + PZD2) Sum : 16 Bytes

Start Delay The length of the start delay is at least the time of two characters and depends on the baudrate.

Table 6-39 Length of start delay

Baudrate in bit/s Transfer time per character (= 11 bit) Transfer time per bit Min. Start Delay 9600 1.146 ms 104.170 µs > 2.291 ms 19200 0.573 ms 52.084 µs > 1.146 ms 38400 0.286 ms 26.042 µs > 0.573 ms 57600 0.191 ms 17.361 µs > 0.382 ms 187500 0.059 ms 5.340 µs > 0.117 ms

Note: The time between characters must be smaller than the start delay.

STX The STX field is a single byte ASCII STX character (0x02) used to indicate the start of a message.



LGE The LGE is a single byte field indicating the number of bytes, which follow this in the message. According to the USS specification, the telegram length is variable, and the length must be specified in the 2nd telegram byte (i.e. LGE). Depending on the configuration, fixed telegram lengths can be defined (see description of use data area). Different telegram lengths can be used for different slave nodes on the bus. The maximum total length of a telegram is 256 bytes. The LGE is defined as the use data characters (quantity n), address byte (ADR) and the block check character (BCC). The actual total telegram length will of course be two bytes longer than the LGE as the STX and LGE bytes are not counted in the LGE. Variable length telegrams and fixed length telegrams can both be used. This can be selected using parameters P2012 and P2013 to define the PZD and PKW lengths. Most common fixed length applications will use a 4-word (8-byte) PKW area and a 2-word (4-byte) PZD area giving 12 use data characters. This gives the LGE = 12 + 2 = 14.

ADR The ADR field is a single byte containing the address of the slave node (e.g. inverter). The individual bits in the address byte are addressed as follows:

7 6 5 4 3 2 1 0

Special Mirror Broadcast 5 address bits

Bit 5 is the broadcast bit. If it is set to 1, the message is a broadcast message and will be acted upon by all inverters on the serial link. The node number is not evaluated. The USS protocol specification requires certain settings in the PKW area, refer to the later example on using USS broadcast mode. Bit 6 = 1 indicates a mirror telegram. The node number is evaluated and the addressed slave returns the telegram unchanged to the master. Bit 5 = 0 and bit 6 = 0 and bit 7 = 0 means normal data exchange for units. The node number (bit 0 … bit 4) is evaluated.

BCC BCC means block check character. It is an exclusive OR (XOR) checksum over all telegram bytes except the BCC itself.



6.6.4 Use data area of USS telegram

Basic USS parameters General rule: Index[0] for USS on RS485, Index[1] for USS on RS232.

P2010 USS Baudrate [2400 … 115200] baud P2011 USS Slave Address: [0 … 30] P2012 USS PZD Length: [0 … 2 … 8] words P2013 USS parameter channel length: [0, 3 (3 words), 4 (4 words), 127 (variable

length)] P2014 USS Telegram Off-Time: [0 … 65535] ms. ‘0’ = no timeout check! R2015 Received PZD via USS on RS232 P2016 BICO Selection for PZDs to be sent via USS on RS232 R2018 Received PZD via USS on RS485 P2019 BICO Selection for PZDs to be sent via USS on RS485 r2032 Control Word 1 from USS on RS232 r2033 Control Word 2 from USS on RS232 r2034 Control Word 1 from USS on RS485 r2035 Control Word 2 from USS on RS485

Use data structure The use data area of the USS protocol is used for transferring the application data, which are the parameter channel and process data (PZD). The application data occupies the bytes within the USS frame (STX, LGE, ADR, BCC). The size of the application data can be configured by parameters p2013 and p2012. The following figure shows the structure and order for the parameter channel and process data (PZD).

Figure 6-19 USS Application Data



The length of the parameter channel is determined by parameter P2013, that for the process data by parameter P2012. If either no parameter channel or no PZD is required, the corresponding parameters can be set to zero ("PKW only" or "PZD only" respectively). It is not possible to transmit "PKW only" and "PZD only" alternatively. If both channels are required they must be transferred together.

6.6.5 USS Parameter Channel

Parameter channel The USS protocol defines for the inverters, the use data structure with which a master can access the inverter slaves. The parameter channel can be used to monitor and/or change any parameter in the inverter. For detailed information, refer the section "Data Structure of the Parameter Channel".

Figure 6-20 Structure of the parameter channel in the telegram structure

Parameter value (PWE) For acyclic communication via USS, the number of PWEs can vary. For 16 bit values one PWE is required. If 32 bit values are exchanged, two PWEs are required.

Note Data types U8 will be transferred as U16 with the upper byte zero. Arrays of U8 will therefore require one PWE per index.

A parameter channel for 3 words is a typical data frame for exchanging 16 bit data or alarm messages. The mode with a fixed word length of 3 is used with p2013 = 3. A parameter channel for 4 words is a typical data frame for exchanging 32 bit data variables and requires p2013 = 4. A parameter channel for a flexible word length is used with p2013 = 127. The length for telegrams between master and slave can have a different number of PWEs. If the length of the parameter channel is fixed (p2013 = 3 or 4), then the Master must always correctly send either 3 or 4 words in the parameter channel. Otherwise, the slave will not respond to the telegram. The slave response will be either 3 or 4 words as well. If a fixed length is used, this should be 4, as 3 would not be sufficient to support many of the parameters (i.e. double words). For variable length of the parameter channel (p2013 = 127) the master sends only the necessary number of words for the task in the parameter channel. The length of the response telegram will also only be as long as necessary.



6.6.6 Timeouts and other errors

Telegram Timeouts For the timeout monitoring, the character run time is important:

Table 6-40 Character run time

Baudrate in bit/s Transfer time per character (= 11 bit) Transfer time per bit Character run time 9600 1.146 ms 104.170 us 1.146 ms 19200 0.573 ms 52.084 us 0.573 ms 38400 0.286 ms 26.042 us 0.286 ms 187500 0.059 ms 5.340 us 0.059 ms

The following figure shows the meaning of the "residual run time":

start delay! Residual run time < 1.5 * (n + 3) * character run time (where n = number of data bytes) "Slave Transmitting"/ "Master Transmitting"

is the sum of "Start delay", "Response delay" and "Residual run time"

The master must check the following times:

• "Response delay" = reaction time of slave to USS request • "Residual run time" = transmission time of response telegram sent by slave

The slave must check the following times:

• "Start delay" = timeout between USS messages • "Residual run time" = transmission time of request telegram coming from master

: : :

: : :

: : :

Figure 6-23 Timeout Checks on USS Slave

The timeout margins that are verified on the USS slave are shown in the figure above. "crt" stands for "character run time". The factor "1.5" is the maximum margin. The "start delay" and the minimum "response delay" are fixed minimum values in software. The "residual run times" are monitoring values that cause a timeout if they are exceeded by the character reception.



Process Timeouts Parameter P2014 determines the timeout in ms. A value of zero disables the timeout check. Parameter P2014 checks the cyclic refresh of Bit10 in control word 1. When USS is configured as command source of the drive and P2014 is not zero, Bit10 of the received control word 1 is examined. If the bit is not set, an internal timeout counter is incremented. If the threshold of p2014 is reached, a process timeout fault is set by the drive.

Other errors P2025 = USS rejected P2026 = USS character frame error P2027 = USS overrun error P2028 = USS parity error P2029 = USS start not identified P2030 = USS BCC error P2031 = USS length error



6.6.7 USS Process Data Channel (PZD)

Description In this area of the telegram, process data (PZD) are continually exchanged between the master and slaves. Dependent of the direction the process data channel contains data for a request to the USS slaves or for a response to the USS master. In the requests are control words and setpoints for the slaves and in the responses are status words and actual values for the master.

Figure 6-24 Process data channel

The number of PZD words in a USS-telegram are determined by parameter P2012, where the first two words are: Control word 1(STW1) and main setpoint (HSW) Status word 1 (ZSW1) and actual value (HIW) If P2012 is greater or equal to 4 the additional control word (STW2) is transferred as the 4th PZD word (default setting). The sources of all other PZDs are defined with parameter P2019 for a RS485 interface and P2016 for a RS232 interface.


Operation 77.1 ON/OFF commands

OFF functions of SINAMICS G120 The G120 inverter provides the following OFF functions: ON / OFF (ON/OFF1) Coast stop (OFF2) Quick stop (OFF3)

Description ON / OFF (ON/OFF1) The ON/OFF1 function is a closely coupled command. When the ON command is withdrawn, then OFF1 is directly activated. Frequency setpoint = 0

The inverter ramps down to standstill in the period of time set in P1121. If parameterized, the motor holding brake is closed (P1215) when zero speed is detected.

When the brake application time (P1217) expires, the pulses are suppressed. Zero speed is detected, if one of the following events occur: – The actual speed drops below the threshold (P1226). – The monitoring time (P1227), started when the speed setpoint ≤ speed threshold

(P1226), has expired. Coast stop (OFF2) Instantaneous pulse suppression, the drive coasts to a standstill. If parameterized, the motor holding brake is closed immediately. Power-on inhibit is activated.

Before restarting, an OFF2 must be confirmed, e. g. via the OFF key on the BOP(2 times short or longer than 2 s). For certain applications, it is useful to link the confirmation of an OFF2 or an OFF3 to the ON/OFF function.

Note If after a period of time, set in P1227, an OFF1 or an OFF3 has been unable to ramp down the motor to switch-off frequency (P2167), the system forces an immediate OFF2.



Quick stop (OFF3) Frequency setpoint = 0 The inverter ramps down to standstill in the period of time set in P1135. If parameterized, the motor holding brake is closed, when zero speed is detected. When

the brake application time (P1217) expires, the pulses are suppressed. Zero speed is detected, if one of the following events occur: – The actual speed drops below the threshold (P1226). – The monitoring time (P1227), started when the speed setpoint ≤ speed threshold

(P1226), has expired. Power-on inhibit is activated.

DANGER

During power off, hazardous loads must be secured by a motor holding brake. To avoid severe personal injury and property damage, make sure, that a motor holding brake is established in the drive system. Use SINAMICS G120 brake sequence control (P1215, P0346, P1216, P1217, P1080) to control the motor holding brake during power off.

Sources for ON/OFF command For standard Control Units (CU240S), the command source for ON/OFF is the digital input 0. For PROFINET or PROFIBUS Control Units, the communication interface is used as command source for ON/OFF The ON/OFF command can be given via the following components: Digital inputs BOP STARTER A higher-leveled control system

ON/OFF command via DI/DO Via DI/DO terminals, you can establish and parameterize a switch for the desired ON/OFF functions in a drive system. The ON/OFF functions require a permanent signal.



ON/OFF command via BOP To power the motor on/off, press the following keys on the BOP:

ON

OFF1 Press once

OFF2 Press twice or pressing once for a longer period of time

ON/OFF command via a higher-level control system Via a serial interface, you switch on/off the inverter output using a higher-level control system, e. g. a SIMATIC S7-300.

Note The 2-/3-wire control provides special ON/OFF methods. For detailed information, refer to the Function Manual.

Troubleshooting 88.1 Faults and Alarms

Description The inverter indicates unfavourable states as faults and alarms. Alarms

Alarms are not displayed via the LEDs on the Control Unit. Alarms require no acknowledgement and cause no systems reaction. The alarm number is displayed on STARTER or a higher-level control system.

Faults Faults indicate a severe unfavourable state. If a fault occurs, the inverter powers off and the LED "SF" on the Control Unit is active. The fault number is displayed on BOP, STARTER or a higher-level control system. You cannot restart the inverter not until the fault is remedied. After remedy the fault requires an acknowledgement.

Note For detailed descriptions of the faults and alarms, refer to the Parameter Manual

Parameterizing faults and alarms

Faults For fault handling, regard the following parameters: Stored in parameter r0947 under their code number, e. g. F0003 = 3 Associated error value stored in parameter r0949 (0 = no error value) Time stamp of the fault stored in r0948 and can be read out Number of fault messages (P0952) is stored in r0947 and can be read out

Troubleshooting


Alarms For alarm handling, regard the following parameter: Stored in parameter r2110 under their code number and can be read out, e. g. A0503 =

503. The value 0 indicates, that no warning is applied. Via the index, you have access to the two actual alarms and the last two historical alarms.

Display Faults and alarms are displayed on the following components: BOP

The status display of the BOP indicates the occurring faults and alarms. If several messages arise, the display scrolls constantly through all active faults.

STARTER The detail view in the alarms tab displays information, faults and alarms in the table. In th.e field "messages" the fault or information/alarm text is displayed in plain text.

A higher-level control system. For detailed information, refer the respective manual of the control system.

General acknowledgement of faults To reset the fault code, one of the following methods can be used: Power cycle the inverter.

(Switch OFF/ON the main supply voltage and the external 24 V supply for the Control Unit.)

Press the key FN on the BOP. Activate the default setting of DI 2. Set bit 7 in control word 1 (r0054).

Special acknowledgement of faults The following faults messages can only be acknowledged by a power cycle: F00051 Parameter EEPROM fault F00052 Power stack fault F00061 Automatic Download, MMC is not fitted F00062 Automatic Download, MMC contents invalid F00063 Automatic Download. MMC contents incompatible F00064 Drive attempted to do an Automatic Download during startup F01601 System startup error

Note The drive cannot resume operation until all active faults have been acknowledged. Clearing F00395 is described in the section "Message F00395" of this manual.

Troubleshooting


8.3 Troubleshooting with the BOP

Diagnostics using alarm and fault numbers The BOP must be fitted to the Control Unit. If an alarm or fault condition occurs, the BOP displays appropriate alarm or fault number. If an alarm occurs the alarm number will be displayed and the inverter will continue to run, although it is possible that it may run in an unexpected manner depending upon the alarm condition. If a fault occurs, the fault number will be displayed and the inverter will be stopped. If a line supply failure interrupts commissioning, then inconsistencies can occur regarding the parameterization. In this case, it is important that the commissioning is re-started with a factory reset to establish the original factory settings.

Spare parts/Accessories 1111.1 Basic Operation Panel

Basic Operator Panel (BOP) The BOP is a parameterization tool that is fitted directly to the SINAMICS G120 inverter via the option port. It can also be used for up and download of parameter sets. For a detailed description refer to chapter "Commissioning with the BOP".

Appendix A.1 Electromagnetic Compatibility


11.2 PC Connection Kit

PC Connection Kit The PC Connection Kit is used to connect a PC, with STARTER software, to the inverter via the Option Port. It consists of a 9-pin sub-D socket, a null modem cable (3 m) and a PC inverter connector module. So it is possible to provide the followoing operations To parameterize the inverter (Commissioning, optimizing) To monitor the inverter (Diagnosis) To control the inverter (For the purpose of testing, STARTER has the priority to control)

Figure 11-1 PC-Connection-Kit

Appendix A.1 Electromagnetic Compatibility


11.3 Micro Memory Card (MMC)

Micro Memory Card (MMC) The MMC is used to safe parameters from a Control Unit. Thus saved parameter set can be transferred to another Control Unit. In the case of service, the drive system is immediately ready for use, e. g. after swapping an inverter. The MMC stores up to 100 parameter sets and supports series commissioning without using additional commissioning tools as BOP or STARTER. The commissioning of MMC depends on user settings (Parameter p8458)

Note The inverter can be operated with or without MMC plugged in.

Figure 11-2 MMC


Appendix AA.1 Electromagnetic Compatibility

Electromagnetic compatibility All manufacturers/assemblers of electrical apparatus which "performs a complete intrinsic function and is placed on the market as a single unit intended for the end user" must comply with the EMC directive EC/89/336. There are three routes for the manufacturer/assembler to demonstrate compliance:

Self-certification This is a manufacturer's declaration that the European standards applicable to the electrical environment for which the apparatus is intended have been met. Only standards that have been officially published in the Official Journal of the European Community can be cited in the manufacturer's declaration.

Technical construction file A technical construction file can be prepared for the apparatus describing its EMC characteristics. This file must be approved by a ‘Competent Body’ appointed by the appropriate European government organization. This approach allows the use of standards that are still in preparation.

EMC Standards The SINAMICS G120 drives have been tested in accordance with the EMC Product Standard EN 61800-3:2004.

Appendix A.2 Definition of the EMC Environment and Categories


A.2 Definition of the EMC Environment and Categories

Classification of EMC performance The EMC environment and categories are defined within the EMC Product Standard EN 61800-3, as follows:

First Environment An environment that includes domestic premises and establishments that are connected directly to a public low-voltage power supply network without the use of an intermediate transformer.

Note For example: houses, apartments, commercial premises or offices in a residential building.

Second Environment An environment that includes industrial premises and establishments that are not connected directly to a public low-voltage power supply network.

Note For example: industrial and technical areas of buildings fed from a dedicated transformer.

Category C1 Power Drive System (PDS) of rated voltage less than 1000 V intended for use in the First (Domestic) Environment.

Category C2 Power Drive System (PDS) of rated voltage less than 1000 V, which is neither a plug in device nor a movable device, and when used in the First (Domestic) Environment, is only intended to be installed and commissioned by a professional.

Note A professional is a person or an organization having necessary skills in installing and/or commissioning a Power Drive System (PDS), including their EMC aspects.

Appendix A.3 EMC Overall Performance


A.3 EMC Overall Performance

EMC Emissions The SINAMICS G120 drives have been tested in accordance with the emission requirements of the category C2 (domestic) environment.

Table A-1 Conducted & Radiated Emissions

EMC Phenomenon Standard Level Conducted Emissions EN 55011 Class A Radiated Emissions EN 55011 Class A

Note To achieve this performance the default switching frequency should not be exceeded. In order to achieve conducted emissions to EN 55011 Class B there is a range of PM240 external filter options available.

Achieving radiated emissions to EN 55011 Class B is largely dependent on the drive being correctly installed inside a metallic enclosure. The limits will not be met if the drive is not enclosed or installed in accordance with good EMC practices.

Harmonic Currents The harmonic current emissions from the SINAMICS G120 drives is as follows:

Table A-2 Harmonic Currents

Rating Typical Harmonic Current (% of rated input current) 5th 7th 11th 13th 17th 19th 23rd 25th FSA … FSF (400 V, 370 W … 90 kW)

73 52 25 23 22 15 12 10

Note Units installed within the category C2 (domestic) environment require connection to the public low-voltage power supply network. Please contact your local supply network provider.

Units installed within the category C3 (industrial) environment do not require connection approval.
